Question

Implement the Boolean expression f(a, b, c) = ∑ m(0, 2, 5, 6) using 4 : 1 multiplexer.​

Answer 1

Answer:

In the given boolean expression, there are 3 variables. We should use 23 : 1 = 8 : 1 multiplexer. But as per the question, it is to be implemented with 4 : 1 mux.

For 4 : 1 multiplexer, there should be 2 selection lines. So from the given 3 variables, the 2 least significant variables(B, C) are used as selection line inputs.
