How do you make and use mux?

All we need to do is zero out the second product term. We can achieve this by making B as ‘0’. We can tie B input of MUX to zero. Thus we can get an AND gate by tying B input of MUX to zero, resulting circuit is AND gate which ANDs input A and mux select S.

What is the formula of mux?

2n : 1 MUX requires (2^n – 1) 2 : 1 MUX. In general, to implement B : 1 MUX using A : 1 MUX , one formula is used to implement the same. KN-1 / A = KN = 1 (till we obtain 1 count of MUX).

How do you solve mux problems?

How to solve?

1. The first step is to select the multiplexer.
2. Connect the inputs, that correspond to the given minterms to logic 1.
3. Connect all the other inputs to the ground(logic 0).
4. Connect the input variables(P, Q, R) as the selection lines.

How are select lines calculated in mux?

A set of inputs called select lines determine which input should be passed to the output. For a 2:1 (two-to-one) MUX, when sel is 0, q = a and when sel is 1, q = b. A multiplexer with 2N input lines requires N select lines.

What are the applications of MUX?

Applications of Multiplexers

• Communication System. A communication system has both a communication network and a transmission system.
• Computer Memory.
• Telephone Network.
• Transmission from the Computer System of a Satellite.
• Communication System.
• Arithmetic Logic Unit.
• Serial to Parallel Converter.
• Photo Credits.

How does a 4 1 mux work?

A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. The select lines S0 and S1 select one of the four input lines to connect the output line.

How do you find the output of a MUX?

Multiplexer is a combinational circuit that has maximum of 2n data inputs, ‘n’ selection lines and single output line. One of these data inputs will be connected to the output based on the values of selection lines….4×1 Multiplexer.

What is demultiplexer Geeksforgeeks?

Demultiplexer is a data distributor which takes a single input and gives several outputs.In demultiplexer we have 1 input and 2n output lines where n is the selection line.
