Is the following question correct?

Consider the Boolean expression F(A,B,C) = ABC+ AB+ AC.

Implement this logic expression using one 4x1 multiplexer. Do not use C as an input to the selectors of the multiplexer.

No, I wouldn't use that method. Instead,

  • Simplify the given function
  • Since you can't connect C, connect A and B to the select inputs of the multiplexer.
  • Figure out what needs to be connected to each of the four multiplexer data inputs. The choices are 0, 1 or C.
