7. (8) A4 bit adder is shown below. It produces the sum (S) of two 4-bit numbers (x and y). Design a circuit that produces the sum of three 4-bit numbers by interconnecting several 4-bit adders. You do not need to know or show the internal circuitry of the 4 bit adder circuit. The numbers you are to add are: (A3 A2 Aj Ao, B3 B2 B1 Bo, C3 C2 C1 Co) as shown.
