Animation of xnor gate

An XNOR gate is a one whose output is high only when all its inputs are the same, i.e. either all the inputs are low or all the inputs are high. In all other cases, when the inputs don't match, the output remains low. It can be looked at as a combination of a XOR and NOT gate.
It is represented by the symbol
The following truth table and animation depict the operation of the XNOR gate.
