An XNOR logic gate has two inputs A and B. When both A and B are HIGH (logic 1), the output Y1 is obtained. When both A and B are LOW (logic 0), the output Y2 is obtained. What is the pair (Y1, Y2)?

Question

Accepted Answer

1, 1. For an XNOR gate, Y = NOT(A XOR B). When A = B = 1: A XOR B = 0, so Y = NOT(0) = 1. When A = B = 0: A XOR B = 0, so Y = NOT(0) = 1. Both cases give output 1, so (Y1, Y2) = (1, 1).
