What is the truth table of 4 1 multiplexer?
The truth table of a 4-to-1 multiplexer is shown below in which four input combinations 00, 10, 01 and 11 on the select lines respectively switches the inputs D0, D2, D1 and D3 to the output. That means when S0=0 and S1 =0, the output at Y is D0, similarly Y is D1 if the select inputs S0=0 and S1= 1 and so on.
What is a 1 of 4 demultiplexer?
A 1-to-4 demultiplexer has a single input (D), two selection lines (S1 and S0) and four outputs (Y0 to Y3). The input data goes to any one of the four outputs at a given time for a particular combination of select lines.
How many and gates are required for a 1 demux?
7. How many AND gates are required for a 1-to-8 multiplexer? Explanation: The number of AND gates required will be equal to the number of outputs in a demultiplexer, which are 8.
What will be the output of 4 1 mux if the value in selection lines s0 1 and s1 1?
4×1 Multiplexer: In the 4×1 multiplexer, there is a total of four inputs, i.e., A0, A1, A2, and A3, 2 selection lines, i.e., S0 and S1 and single output, i.e., Y. On the basis of the combination of inputs that are present at the selection lines S0 and S1, one of these 4 inputs are connected to the output.
How number of select lines are required for a 1 to 4 demultiplexer?
Therefore, for 1:4 demultiplexer, 2 select lines are required. Explanation: A demultiplexer sends a single input to multiple outputs, depending on the select lines. As the select input changes, the output of the multiplexer varies according to that input.
Which is the symbol of OR gate?
The logic or Boolean expression given for a digital logic OR gate is that for Logical Addition which is denoted by a plus sign, ( + ) giving us the Boolean expression of: A+B = Q.
How many select lines will be there if the inputs of a DEMUX are 4?
2 select lines
of select lines. Therefore, for 1:4 demultiplexer, 2 select lines are required. Explanation: A demultiplexer sends a single input to multiple outputs, depending on the select lines. As the select input changes, the output of the multiplexer varies according to that input.
How many not gates are required for the construction of a 4 to 1 multiplexer?
two NOT gates
Explanation: There are two NOT gates required for the construction of 4-to-1 multiplexer. x0, x1, x2 and x3 are the inputs and C1 and C0 are the select lines and M is the output.
How many and gates are required for a 1 to 8 DEMUX?
8 AND gates
For a 1 to 8 multiplexer a total of 8 AND gates are required.
How many gates are required for the construction of a 4 to 1 multiplexer?
