47. *Implement the Boolean function F(A,B,C,D) = m(1,3,4, 11, 12, 13, 14, 15) with a 4-to-1-line multiplexer and external gates. Connect inputs A and B to the selection lines. The input requirements for the four data lines will be a function of the variables C and D. The values of these variables are obtained by expressing F as a function of C and D for each of the four cases when AB 00, 01, 10, and 11. These functions must be implemented with external gates.
