ANSWER :
(c) A∩B∩(C∪B)'
First we will solve (C∪B)'
C∪B = {1,3,4,7}∪{1,2,4,6} = {1,2,3,4,6,7}
(C∪B)' = U - (C∪B ) = {5,8}
B∩(C∪B)' = {Φ}
A∩B∩(C∪B)' = {Φ}
(d) A∩B∩C'∪B
C' = U - C = {2,5,6,8}
C'∪B = {1,2,4,5,6,8}
B∩C'∪B = {1,2,4,6}
A∩B∩C'∪B = {1,2}

1. [20 Pts] You are given the data-path below. Note that there are three registers. Two of these have a load control input, while the other loads a new value on every clock cycle. There are two tri-state drivers that connect the outputs of registers A and Bto a common bus. Finally, there is an ALU that can perform two operations: .Pass Y add X and Y X is always the output of register C, while Y is the value...
