when two variables are logically compared , the logic gate that tests the equivalence is ___

A XNOR
B XOR
C AND
D NOR

Correct Answer: XOR

This explains why "EQ" is often called "XNOR" in the combinational logic of circuit engineers, since it is the negation of the XOR operation; "NXOR" is a less commonly used alternative. Another rationalization of the admittedly circuitous name "XNOR" is that one begins with the "both false" operator NOR and then adds the eXception "or both true".
