## How would you implement a Boolean function with multiplexer?

Implementation of SOP function using multiplexer

- Step 1: Draw the truth table for the given number of variable function.
- Step 2: Consider one variable as input and remaining variables as select lines.
- Step 3: Form a matrix where input lines of MUX are columns and input variable and its compliment are rows.

## How do you implement a Boolean function?

Any Boolean function can be implemented using only AND and INVERT gates since the OR function can be generated by a combination of these two gates, as shown in Figure 2.20(a). It follows that these two gates can implement any arbitrary Boolean function and they are said to form a complete set.

**How Boolean is implemented using decoder?**

Combinational Logic Implementation using Decoder – Since any boolean function can be expressed as a sum of minterms, a decoder that can generate these minterms along with external OR gates that form their logical sums, can be used to form a circuit of any boolean function.

### Which form is preferable when implementing a Boolean function with gates?

Explanation: Standard form would be preferred over canonical form since it is more simplified and requires less gates.

### What is difference between multiplexer and decoder?

Decoder is a logic circuit which n input lines into m output lines….Difference between of Multiplexer and Decoder :

S.NO. | Multiplexer | Decoder |
---|---|---|

1. | MUX accepts several inputs and allow only one data output. | It takes n input binary code and convert it into a corresponding outputs. |

**What is the use of multiplexer and demultiplexer?**

The basic function of a multiplexer: combining multiple inputs into a single data stream. On the receiving side, a demultiplexer splits the single data stream into the original multiple signals.

## What are the applications of multiplexer and demultiplexer?

Demultiplexer uses the control signal to permit us to include several outputs. The multiplexer is used to improve the efficiency of the communication system using transmission data like transmission of audio as well as video.
