D-Type Flip Flop Circuit Diagrams in Proteus

Hey Mentees! Welcome from the team of The Engineering Projects. We hope You are having a reproductive day. To add more reproduction, let's learn another Logical Circuit from scratch. In this Tutorial, we'll grasp the following topics:

1. What are D-Type Flip Flop?
2. Which is the IC of D Flip Flop in Proteus ISIS?
3. How is the working of D Flip Flop?
4. How can we design the Truth Table of D Flip Flop?
5. How can we Perform the formation of D Flip Flops in Proteus ISIS?

Moreover, we'll have small chunks of information in DID YOU KNOW Sections. At this instance, Let's start the learning.

D-Type Flip Flops

D-Type Flip Flops are important Logical Circuits and we Introduce it as:

"The D-Type Flip Flop is a type of Flip Flop that captures the value of D input for a specific time of the Clock edge and show the output according to the value of D at that time."

D-Type Flip Flops have the ability to Latch or delay the DATA inputs and therefore are the improved version of the SR Flip Flop (In which the data shows the Invalid output when the inputs are HIGH) . Recall that Flip Flops are the Logical Circuits that can hold and store the data in the form of bits and are important building blocks of many of electronic devices and circuits.

DID YOU KNOW???????????????????????? The D Flip Flop is also known as the Data Flip Flop.

When we observe the circuit of D Flip Flop we observe 2 Important points in the D flip Flops:

1. The D Flip Flop is the circuit of active High SR Flip Flop that have the S and R inputs connected together with an invertor gate so that both S  and R (looking with the point of view of SR Flip Flop) will always have the opposite state to each other.
2. The circuit has only one input called D input and it always has a clock that has one of the major effect at the output of D Flip Flop.

D Flip Flop IC

IC's play a magical role in the world of electronics. They make the circuit so simple and decrease the chances of the errors in the circuit. for D Flip Flop, the IC Used has a number CD4013 and for better understanding, D Flip Flop IC named 4013 is shown in the Proteus software in the image below: The S and R are the additional pins to use it for the higher level Experiments. Yet for the simplicity and core information, we'll use Logic Gates when we'll perform in the practical section.

Working of D Flip Flop

In the working of D type Flip Flop, we observe that the D is the only input of the D Flip Flop. yet, the Clock also has the effect in the output of the circuit. Due to the Latched Circuit of Flip Flops, all this discussion would be pointless if we took the concept in the mind that at every pulse, the data of the Flip Flop is changed. Truss, we use an Enabler or Clock in the Circuit through which we can separate the circuit from the input at the instance of our will. When clock is HIGH: Thus, when the D is set HIGH the circuit is said to be in the "Set" State. By the same token, when the D input is LOW the circuit is said to be in the "Reset" position. Unlike SR Flip Flop, the output Q is same as the value of D input and Q' is the vise versa. When Clock is LOW: During the operation when the Clock or Enable input is LOW, any value at the D does not have any effect on the circuit's output. This position is called the "Don't Care" State of D Flip Flop.

Truth Table of D Flip Flop

Based upon the Concepts given above, one can easily design the Truth Table of the D Flip Flop. Let's have a look at the Truth Table.

Inputs		Output
CLK	D	Q	Q’
0	X	No Change
1	0	0	1
1	1	1	0

For the purpose of best understanding, we are going to check these concepts and the circuit information in the simulation Software. We are using the Proteus ISIS here.

Performance of D Flip Flop i Proteus ISIS

To perform the experiment in the software, just follow the simple steps given next.

Material Required

1. NAND Gate
2. NOT Gate
3. Logic Toggle
4. LED-RED
5. Ground Terminal
6. Connecting wires

• Fire up your Proteus ISIS.
• Pop the "P" button present at the screen and Write the name of 1st four devices and select them one after the other.
• Arrange four NAND gates and the inverter gate (NOT Gate) at the working area just according to the image given below:

• Take Logic Toggles and arrange them just at the left side of the system.
• Get the LED's for the output and connect one of them with the output of switch Q and Q'.
• Go to Terminal mode>Ground, attach the one ground Terminal with each the LEDs.
• Connect all the devices according to the diagram given next:

• Change the value of the Clock and observe does the value of the output change?
• Turning the LED on means the output is HIGH and vise versa.
• For convenience, the D Flip Flop can also be obtained by using a NAND as NOT in the Circuit as shown in figure:

DID YOU KNOW?????????????

In real life, the Clock is used in the place of Logic Gate (as shown in the image above) because it automatically changes the direction and change the output of the D Flip Flop. 

NOTE: You can also use the Logic Probe instead of the Grounded LED. Truss, in this session, we saw what are the D Flip Flops, how does they work, how an we design the Truth Table of D Flip Flop and how can we perform it practically in Proteus ISIS. In the next session, we'll know what are T Flip Flop and how is its Simulation in Proteus ISIS.

Emerging Opportunities In Stocks Trading With Innovative Ideas

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the emerging opportunities in stocks trading with innovative ideas. 2020 has unleashed the entire world on the battlefield of uncertainty. You cannot assure how companies and firms will evolve in the coming days. With this pandemic, influencing both personal and professional life, our future is not certain. This uncertainty has affected stock trading and the factors influencing it.

Emerging Opportunities In Stocks Trading With Innovative Ideas

Trading is generally considered a risk profession but this is not the case as per innovation in technology. Now, you can easily trade to make profits even if you have little to no money. There are many online services available like Automatic Fortunes, which help users in emerging opportunities in the stock trading market. Participating in a potential growth stock can help you grow financially With trading, you can generate passive income or take it as a full-time job or part-time opportunity, either way, you have a massive chance to make a handsome amount of money.

1. Innovative Technology

Needless to say, advancement in technology has produced plenty of low barriers-to-entry trading opportunities. You can do trading with no money in some cases. While in other cases, little money is needed to put you on the steering wheel of trading. Anyone with patience and commitment can make a killing in this profession. Innovation is introducing a new idea to bring ease and comfort to people’s life. New internet technology has turned the entire world into a global village, interlinking the global market and giving you the ability to make money right from the comfort of your home. Even if you have a full-time job or have a family to support, you can join stock trading to make a living.

2. Trading Opportunities

Normally stock prices are based on technical indicators that mainly influence the large price movements. This is true, such combinations occur once in a while, but when they do, they bring scores of opportunities for everyone. They are mainly termed as trading opportunities. The opportunities in stock trading generally come with a low downside while the upside is high. Every opportunity in stock trading is measured with a score ranging from 0 to 100. The higher score is linked to better trading opportunities and as a result ensuring more profit with the trade. Still, a higher score doesn’t ALWAYS guarantee more profit because some factors like volume balance, trend direction, support, and resistance also influence the technical aspect of stock. It is, therefore, preferred to see the entire picture of stock trading and, more importantly, audit the basic information before trading. Know that risk factor has nothing to do with the score calculation. Two different stocks that contain the same score may face entirely different risks. Some people assume stock trading is a walk in the park; this is not the case in reality. The success of this business is entirely dependent on you. It involves so many paths, where anybody can join the business. You need to well prepare yourself in advance for all the ups and downs of the stock trading.

A. Trading from Home

This seems like the best and easiest way to earn a living because you have flexible hours to work but there is a catch. The minimum equity required for trading to work as a pattern day trader is 25000$. And you need to maintain this amount all the time. If your account fails to retain this minimum, your account will be put on hold until you hit the minimum once again.

B. Proprietary Trading Firms

These firms have become famous among the masses due to their attractive and low-free strategies. If working from home is not your cup of tea, you might want to join the trading floor where you can typically work as a contractor. You’ll never get a daily wage in firms like these, just the commission you make bringing clients to the firm for trading. There are plenty of benefits to working in a trading company including exposure to trading ideas, meeting with successful traders, free training, performance monitoring, and easy access to capital.

C. Other Options

When you don’t have enough money to invest, it’s wise to get a hold of other trading options that demand less capital. The currency markets and foreign exchange are the best alternatives that require less capital where you can open an account in just $100, helping you control a large amount of money with this capital. These markets work 24/7, giving you the flexibility to collaborate from anywhere anytime. These markets are mainly introduced for the traders who don’t have time to work in regular working hours.

Conclusion

Once you’ve got to know which trading option suits you the best, stick with it. If trading from home resonates with you, make sure the markets you trade with will lie within your interests and capital. And come up with a comprehensive trading plan to get a hold of all complexities in your trading business. This is now your business. You need to apply everything in this business you would otherwise apply in regular business. Work with online brokers and explore other options. If you have a laptop and internet connection, you can make a living trading. Last not least, don’t hesitate to get help from the mentors. They will help you stay on track and how to deal with the challenges you might face in trading. That’s all for today. Hope you find this article helpful.

How to Leverage the Full Benefits of B2B e-Commerce for Your Business

Hello Pals! We welcome you at The Engineering Projects. We Hope you are fine. We are going to learn about the Benefits of B2B e-commerce. Despite the rapid growth of the B2B market, especially compared to its B2C counterpart, we’re still seeing a surprisingly low adoption rate of modern e-Commerce solutions on that front. Which is unfortunate for the companies that are still failing to adopt those solutions, as it’s resulted in many of them lagging behind their competitors. On the bright side, this has created a great opportunity for those willing to go the extra mile, as investing in a competent, modern B2B e-Commerce solution can result in numerous benefits, some of which will be visible almost immediately. 

Focus on the Customer’s Experience

A lot can be done to improve the customer experience in a typical B2B operation, and ensuring that people have everything they need to do their research under one roof can go a long way towards improving your standing with your users. A good B2B e-Commerce system can provide your customers with various valuable insights, including product reviews, aggregate scores, detailed information, as well as specifics related to your business itself, like shipping rates, handling details, and more. Customers are used to doing their own research in these areas nowadays, but this doesn’t mean that you can’t provide them with an enticing reason to stick to your own storefront for those purposes. What’s more, you can make each customer’s experience customized and fine-tailored to their specific needs and interests, driving up your retention rates far above what can be accomplished with a static storefront.

Easy Handling of Growth

While every business strives for growth in the long term, it can also be a double-edged sword for those who are not adequately prepared for it. Uncontrolled growth can even kill your entire business in more extreme cases. With a good e-Commerce solution, you can negate many of the dangers that come with rapid growth, allowing you to quickly open new stores, expand your current ones, and leverage different selling modes to ensure that you’re covering all your fronts. This is something you can typically do on your own, admittedly – but it will cost you significantly more in terms of time and other resources needed to get there. You can more easily focus on the complex parts of your business that require your constant attention when your mind is not constantly preoccupied with the issues that arise in the course of expanding.

More Informed Decisions

The ability to make accurate decisions based on reliable information and analysis is crucial for staying afloat in the B2B market, and that’s another point which can be assisted greatly by the use of a modern B2B e-Commerce solution. You can easily consolidate all the data you’re generating from your different areas of operation, and ensure that you’re always seeing the big picture when making any critical decisions for the development of your company. In some cases, you’ll even have a better idea of what’s coming up ahead compared to the majority of your competitors, thanks to advanced approaches to data analysis. You won’t have to worry about introducing new data collection and aggregation points either, as you’ll have reassurance that you’ll be able to work with all new pieces of information that come your way.

The Power of Automation

Many of the tasks you perform in your day-to-day operations can be automated nowadays – and that’s something which can increase your productivity by a large margin if handled correctly. Your B2B e-Commerce solution will handle all standard parts of the shopping and purchase process, sometimes even including basic interaction with your customers (e.g. through the use of AI-driven chatbots). This will allow you to invest more of your time into the areas that actually require critical thinking and an informed approach, instead of wasting your time on menial, repetitive tasks. The same goes for everyone else working in your organization. In fact, a comprehensive e-Commerce suite can help you decrease your need for employees overall, giving you a good opportunity to streamline your operations even further. This can synergize with other points we’ve already mentioned, like your ability to expand into new markets without having to invest that much into each new storefront.

Flexibility in a Dynamic Market

You’re no longer limited to operating within the limits of your physical location these days, and in fact, many of your customers will expect a customized experience that matches their own region if your company is large enough. With the right B2B eCommerce solution, you can effortlessly expand your operations to new areas without constantly having to research new tax laws, country-specific regulations, and other similar details which can change significantly from one place to another. Expanding into a new market altogether is something that would normally require a large investment, but with the help of the right e-Commerce solution, many of the difficult parts of the process can be streamlined. Smooth Integration of Payment Services A common roadblock for many B2B and B2C companies is the wide range of payment services that customers expect to be supported. This gets even more complex as you begin to expand into new markets, many of which may have their own local payment solutions. Your B2B e-Commerce solution should be able to handle most of that for you, providing your customers with a unified payment front that ties into all relevant points of your backend seamlessly. You’ll no longer have to worry about how a certain payment method will be integrated with your accounting software, for example, or bother yourself with processes like identity verification. In many cases, technical issues related to payment providers will be handled by the e-Commerce platform as well. The initial integration of an e-Commerce solution can take a while, but after you’ve gone through that initial effort, you’ll find that everything else usually becomes much more streamlined. And the more you continue to integrate your operations with your B2B e-Commerce solution, the easier it will be to keep the ball rolling and ensure that you continue to offer an experience that’s aligned with your customers’ expectations.

2-to-1 Multiplexer using Logic Gates in Proteus ISIS

Hi Mentees! I welcome you on behalf of The Engineering Projects. In this section of this DLD Logic gates series, we are discussing different applications of logic gates. We have discussed DLD Adders and Subtractors in our previous lectures and now it's time to have a look at DLD Multiplexers.

1. What are Multiplexers?
2. What are the types of Multiplexers?
3. What are the two input Multiplexers?
4. How can we simulate the Circuit of 2 to 2 MUX in Proteus ISIS?
5. How can we use the 2 to 1 MUX as OR, AND and NOT gates?

What are Multiplexers?

When I heard the word Multiplexer, I thought that as Adder adds numbers, Subtractor subtracts numbers, similarly, the Multiplexer will multiply binary numbers but that's not the case. Multiplexer is defined as:

• A Multiplexer(also called MUX or MPX) is a simple digital electronic circuit, designed using DLD Logic Gates and is used to select a single input from multiple inputs provided to it.
• The input selection is controlled by a separate Input called Select Input(S).
• The selected Input is then forwarded to the Output Terminal.
• In a simple two Input(A₁, A₂) MUX,
1. If S = 0, the output(Y) will be A₁
2. If S = 1, the output(Y) will be A₂.

A Multiplexer is also called Data Selector, Universal Logic Selector, Many-to-one Logic converter and Parallel-to-Serial Convertor because it has the ability to select a single input from multiple inputs.

Let's understand the working principle of Multiplexer in detail:

Multiplexer Working Principle

Let's take the example of the simplest multiplexer i.e. 2-to-1 MUX. It has 2 normal inputs(A₁ , A₂ ) and 1 Select Input(S) and it generates single Output(Y). Here's the block diagram of a simple 2-to-1 Multiplexer:

As discussed above, the selection of inputs is controlled by the Select Pin(S). So, if S = 0, the output will be A₁ and if S = 1, the output will be A₂. The relation between Select Input and Output is shown in the below truth table:

Select Input(S)	Output(Y)
0	A1
1	A2

We can understand from the above truth table that we can control maximum 2 inputs from a single Select Input. So, in order to control more than 2 inputs, we need to increase the number of Select Inputs. For example, 2 Select Inputs can control a maximum of 4 Normal Inputs. So, the relation between Select and Normal Inputs can be described by the following formula:

Normal Inputs = 2ⁿ

where, n represents the Select Inputs.

So, if we have 5 Select Inputs, we can easily control 2⁵ = 32 Normal Inputs.

We have discussed its types in our Lecture. 2-to-1 Multiplexer As the name justifies, the 2 to 1 Multiplexer is the one where we have two inputs and only one output. Let's find what are 2:1 MUX. " The kind of Multiplexer or MUX that contains two inputs, one Selector and one Output is called 2-to-1 MUX or multiplexer. The inputs are usually named as D0 and D1, the selector is termed as S and the output is called Y." You can change the names of the inputs and output according to your choice.

Truth Table of 2-to-1 MUX

As we have discussed earlier, the inputs of Multiplexer depends upon a Selector S. therefore, when we design a Truth Table, we include a Selector also in it. While designing a 2-to-1 MUX, we follow the expression given below:

Y=D0S' + D1S

Considering the expression above we get the Truth Table of 2-to-1 Multiplexer as follow:

S	D0	D1	Y
0	0	0	0
0	0	1	0
0	1	0	1
0	1	1	0
1	0	0	0
1	0	1	1
1	1	0	1
1	1	1	1

  On the basis of above discussion, I am going to Produce a 2-into-1 MUX in Proteus ISIS.

Implementing 2-to-1 Multiplexer in Proteus ISIS

To Design a 2-to-1 Multiplexer, we need the following material:

Material Required

1. AND Gate
2. OR Gate
3. NOT Gate
4. Logic Toggle
5. LED
6. Ground Terminal

• Grab the required Material from the Pick Library one after the other by Pressing a "P" button present at the screen.
• Hit and hold the Name of the chosen Logic Gates one by one and arrange them at the screen according to the given image:

• Get Three Logic Toggles and set them just before the Logic Gates.
• Arrange an LED below the OR Gate's output.
• To have a ground Terminal, left click the mouse >Go to Place>Terminal>Ground.
• Join all the Components according to given image below:

• Pop the Play button just at the left corner of the screen and change the input.

NOTE: If your circuit shows the error of duplication, Simply change the names of gate by double clicking them and give them the desired name.

• Change the conditions of the System by changing the values of inputs and observe the output.

One can Use the 2-into-1 Multiplexer as the other Logic Gates. We discuss the usage of 2-into-1 MUX for the following Gates:

1. AND Gate
2. OR Gate
3. NOT Gate

Let's have a detailed way to use the 2-to-1 Multiplexer in the following way.

Implementing OR Gate through 2-to-1 Multiplexer in Proteus ISIS

The MUX Can easily be used to implement Basic Logic Gate. But before that Recall that what is an OR Gate.

"An OR Gate is a two input Logical Gate that give the output LOW only when both the outputs are LOW."

Procedure for the conversion of 2-to-1 Multiplexer into OR Gate

• Fix the value of D0 to 1 all the time.
• Change the Value of the S and D2 according to the Truth Table given below and match the result.

S	D0	D1	Y
0	0	0	0
0	0	1	1
1	0	0	1
1	0	1	1

Notice that the value of output is equals to the AND Gate.

Implementing AND Gate through 2-to-1 MUX in Proteus ISIS

Recall the definition of AND Gate:

" The AND Gate is the one that consist of two inputs and gives the input HIGH only when both the Inputs are HIGH."

Follow the simple steps to use 2-to 1 MUX as an AND Gate.

Steps to use 2-into-1 MUX as AND Gate

• Set the value of D0 as 1.
• Change the values of S and D0 according to table and record your observations.

 

S	D0	D1	Y
0	0	0	0
0	1	0	0
1	0	0	0
1	1	0	1

You can clearly see that the output is same as the AND Gate hence, you can use it as AND Gate.

NOT Gate through 2 to 1 MUX

Prior to start, Let's refresh the definition of NOT Gate in our minds:

"The NOT Gate is a 1 input invertor Logic Gate that gives the output 1 when input is zero and vice versa."

To use the 2 to 1 MUX as NOT Gate, just follow the steps:

• Set the D0 input as 0.
• Set D1 as 1.
• Change the value of S as 1 and zero  one after the other.
• You will Observe that when S=1 the output is 0 and vice versa.
• Hence this is our required result.

You can check our website for the XNOR, XOR and NOR Gate from 2 to 1 MUX in our Tutorials. Consequently, today we leaned interesting Circuits. We saw what are 2 to 1 Multiplexers. We made a circuit of the 2 to 1 MUX and from the circuit, we found how can we use them as OR, AND and NOT logic Gates along with the truth tables of each.
