e.g. To implement the function F(A, B, C)= Σ (1, 2, 5, 7) using MUX using different variable as selection variable.
Let’s now take the variable B for input lines and A & C for selection lines. The min terms with B in compliment form are 0, 1, 4, 5 and the min terms with B in un-complimented form are 2, 3, 6, 7
So we list the min terms as follow:
So the circuit is as follow:
