For each of the following circuits, identify the input combinations that produce an output of 1.

a. A B AB
1 0 1
In this part if we input 1 and 0 to OR gate then we get 1 as a middle result and then this is
attached with XOR gate with second input B and finally we get 1 as a final result. In other cases
we did not get 1 as a result.
b. A B AB
0 1 1
1 1 1
In this part if we input 1...
