What is an XNOR Gate?XNOR Gate definitionAn XOR gate is formed by adding a non-gate to the output end of the XOR gate, which is the basic unit of the digital logic circuit, with two input terminals and one output terminal.Symbol and truth tableThe symbol of an XOR gate reflects the relationship between its input signal and its output signal, and the truth table confirms its consistent input-outputrelationship.Circuit diagramXNOR Gate circuit diagram as shown below
