16. Consider the logic function f(x,y,z) = Em(0,1,5,6) a) Implement f using one 4-way multiplexer; assume that the inputs and their complements are available at the input of the multiplexer. Use x and y as select inputs. b) Draw the circuit of the multiplexer using four AND gates and one OR gate. You must use a decoder (2-input, 4-output) to drive the multiplexer. 17. An 8:1 multiplexer can be constructed from two 4:1 multiplexers and one 2:1 multiplexer as shown below. Complete the corresponding truth table. S. S, S, Y , 4:1 MUX 2:1 MUX Y I 4:1 MUX 18. Consider the following 8-way multiplexer. 0 1 Write F(a.b.c) as sum of minterms F(a, b, c) =
