    I'm just hitting a blank with this and need some help implementing the following equation using a multiplexer:

    F = DC + CB'A' + D'C'A + DBA'

    Would I use an 8-to-1 multiplexer with the 3 select lines D,C & B, and 2 of the input lines A and A', leaving the corresponding lines 0 and 1 respectively?
    OR
    Would I use 4-to-1 multiplexer with the 2 select lines D & C, with the 4 input lines B and B' & A and A' respectively? [After writing this, I'm leaning towards this solution]

    Oh the initial question is to implement the equation:
    F(A,B,C,D) = ∑m(1,3,4,10,12,13,14,15)

    Cheers

    Wouldn't it be simpler if you use just a 16 to 1 mux !!!
    Or maybe I didn't understand your question.
