XNOR link

An exclusive-NOT-OR-link (also XNOR , NXOR or equivalence ) is a term from propositional logic . The overall statement is then true if either all partial statements true or all false. In other words, a (binary) XNOR operation is true if and only if both partial statements deliver the same truth value. The XNOR link is an XOR link followed by a negation .
