QUESTIONS / RESULTS:

1. If the 0 and 1 were inputs for a XOR gate, what would be the output?
Ans. If the 0 and 1 were inputs for a XOR gate, the output will be high (1).
2. If a signal passing through a gate is inhibited by sending a LOW into one of the inputs,
and the output is LOW, the gate is an XNOR .
3. XNOR provides the inverted output of an XOR. TRUE .


CONCLUSION:

The XOR gate and XNOR gate are known as Special gates. We use truth table to examine the
functionalities and working of these gates. In XOR gate, when both inputs are high (1) or low
(0), the output will be low (0) and when one input is high (1) and other is low (0) then the
result will be high (1). In XNOR gate, when both inputs are high (1) or low (0) then the output
will be high (1) and when one input is high (1) and other is low (0) then the output will be low
