# Design a combination circuit

In summary, the conversation revolves around designing a combinational circuit for a small corporation with 7 shares of stock owned by 3 people. Each share entitles its owner to one vote at a stockholders meeting and the shareholders have switches to vote "YES" or "NO". The solution involves using a 7-segment display, BCD-to-7-Segment decoder, and three 8x1 multiplexers (IC 74151) to convert the input from the switches into the BCD input code for the 7447. The conversation ends with a request for the solution and the question of what conditions each multiplexer will satisfy.

hi to all
can anyone help me to solve this problem ?
A small corporation has 7 shares of stock, and each share entitles its owner to one vote at a
stockholders meeting. The 7 shares are owned by 3 people as follows:
Mr.W:1 share
Mr.X:3 shares
Mr.Y:3 shares
Each of these persons has a switch to close (logic-1) when voting “YES” and open (logic-0) when
voting “NO” for his or her share(s).
Design a combination circuit that displays the total number of shares that vote “YES” for each
measure. Use a 7-segment display and a BCD-to-7-Segment decoder to display the number “YES”
votes. Use three 8x1 multiplexers (IC 74151) to design the combinational circuit that converts the input
from the stock owners' switches into the BCD input code for the 7447.

What set of conditions will each multiplexer satisfy?

I would be happy to help you with this problem. A combination circuit is a type of electronic circuit that combines different logic gates, such as AND, OR, and NOT gates, to perform a specific function. In this case, we need to design a combination circuit that can display the total number of "YES" votes from the stock owners' switches.

To do this, we will use three 8x1 multiplexers (IC 74151) to convert the input from the switches into a BCD code. A BCD code is a binary code that represents decimal numbers from 0 to 9. We will then use a BCD-to-7-Segment decoder to convert the BCD code into a format that can be displayed on a 7-segment display.

First, we need to understand how the 8x1 multiplexers work. These multiplexers have 8 input pins (A0-A7) and 1 output pin (Y). Each input pin corresponds to a different switch from the stock owners. The output pin will be the BCD code that represents the number of "YES" votes.

Next, we will connect the output pins of the three 8x1 multiplexers to the inputs of the BCD-to-7-Segment decoder. The BCD-to-7-Segment decoder will then convert the BCD code into a format that can be displayed on the 7-segment display.

To display the number of "YES" votes, we will use the BCD code to light up the corresponding segments on the 7-segment display. For example, if the BCD code is 0001, the first segment of the display will be lit up, indicating that there is one "YES" vote.

In conclusion, the combination circuit will consist of three 8x1 multiplexers, a BCD-to-7-Segment decoder, and a 7-segment display. The multiplexers will convert the input from the stock owners' switches into a BCD code, which will then be decoded and displayed on the 7-segment display. This circuit will accurately display the total number of "YES" votes from the stock owners.

## 1. What is a combination circuit?

A combination circuit is a circuit that combines different types of components, such as resistors, capacitors, and inductors, to perform a specific function. It can include both series and parallel connections and is used to achieve a desired output.

## 2. How do you design a combination circuit?

To design a combination circuit, you must first determine the desired output and the components that are needed to achieve it. Then, you can use circuit analysis techniques, such as Kirchhoff's laws and Ohm's law, to calculate the values of the components and the overall circuit configuration.

## 3. What are the advantages of using a combination circuit?

One advantage of using a combination circuit is that it allows for more flexibility in achieving a desired output. It also allows for the use of a variety of components, which can lead to more efficient and cost-effective designs.

## 4. What are some common applications of combination circuits?

Combination circuits are commonly used in electronic devices, such as computers, televisions, and smartphones. They are also used in power systems to regulate voltage and current and in communication systems to filter and amplify signals.

## 5. What are some tips for troubleshooting a combination circuit?

If a combination circuit is not functioning properly, it is important to check all connections and make sure the components are properly connected. You can also use a multimeter to test the voltage and current at different points in the circuit. Additionally, understanding the principles of circuit analysis can help identify and fix any issues in the circuit.
