Two full-adder implementations are presented in Figure (a) & (b). (1) Prove that these two implementations are functionally equivalent using Boolean theorems. (Hint: Consensus) 2）Which one of the two full-adder implementation above would you choose for your design? Justify your choice. 3）For the implementation you chose, convert the full-adder to a full-subtracter, assuming negative numbers are represented in 2’s complement. (Hint: remind how the subtraction processes in 2’s complement)
