F(A,B,C,D) = ∑m (0,3,4,7,8,9,13,14)
The given function is in terms of minterms and is to be implemented using a 8:1 MUX. An 8:1 MUX has three select lines, whereas the given function is a 4 variable function. Hence a logic is needed to give combination of A as inputs while only B, C and D as select line inputs. The method for the same is described below.
