I have a question that I can't figure out for 2 days. Here is my question: I have 4-variable function (A,B,C,D). I want to implement it using 4x1 mux and external gates. I have to connect A and B to the selection lines. Plus, the four input lines will be the function of C and D for each one of the four possible values of AB.
Implement the function F (A, B, C, D) = Σ (0, 1, 2, 3, 4, 5, 8, 11, 13, 14) using a 4 x 1 multiplexer and external gates. Connect A and B to the selection lines. The four input lines will be a function of C and D for each of the four possible values of AB. You may need external gates to implement these functions. The input lines may also be connected to 0 or 1.
