XNOR gate
The XNOR gate (sometimes spelled "exnor" or "enor" and rarely written NXOR) is a digital logic gate whose function is the logical complement of the exclusive OR (XOR) gate. The two-input version implements logical equality, behaving according to the truth table to the right. A HIGH output (1) results if both of the inputs to the gate are the same. If one but not both inputs are HIGH (1), a LOW output (0) results. ==Symbols== There are 2 symbols for XNOR gates: the 'distinctive' symbol and the 'rectangular' symbol. For more information see Logic Gate Symbols. The ANSI symbol for the XNOR gate is a standard XOR gate with an inversion bubble connected. The XNOR gate with inputs ''A'' and ''B'' implements the logical expression .
