(Multiplexer Implementation) Show how to implement the full adder Sum(A,B,Cin) and Cout(A,B,Cin) in terms of:

(a) Two 8:1 multiplexers


(b) Two 4:1 multiplexers


(c) If you are limited to 2:1 multiplexers (and inverters) only, how would you use them to implement the full adder and how many 2:1 multiplexers would you need?


(d) It is possible to implement the full-adder function with only 5 2:1 multiplexers. Do you see how?
