Q2: Implement the function using MUX

To implement the function F(A, B, C, D)= Σ (1, 2, 5, 7, 9, 14) using MUX using different variable as selection variable.

Let’s now take the variable A for input lines and B, C & D for selection lines.

N=4 so MUX is 2 N-1= 23 = 8 to 1

So min terms with A in compliment form are 0 – 7

So min terms with A in un-compliment form are 8 – 15

So we list the MIN TERMS as:

And the circuit diagram is shown next:
