XNOR gate

An XNOR gate (English eXclusive OR NOT ) is a gate, wherein the output if and only a logical " 1" is present, if at an even number of inputs is "1 " is present, and on the remaining "0". In the case of two inputs at the output exactly then " 1 " when both inputs " 1" or both inputs " 0" is present ( in the second case is due to zero inputs " 1", and 0 counts as even number ). The XNOR operation is also referred to as equivalent, or Biimplikation biconditional.

The XNOR gate can be constructed by an XOR gate with downstream NOT gate (inverter).
