Combinational Logic Analysis - Technical MCQs

Q1:

The output of an exclusive-NOR gate is 1. Which input combination is correct?

A A = 1, B = 0

B A = 0, B = 1

C A = 0, B = 0

D none of the above

ANS:C - A = 0, B = 0

Output equation for the two input(A,B) exclusive-NOR gate is (A.B)+(A bar.B bar)...
substitute input values...
