Xnor

The xnor logic gate is equal to one and zero in input the output. The result 0 when output is equal to 0 the gate doesn't open. If (one and one) and (0 and 0) input the output the result 1 then the gate opens. 1 is called HIGH and 0 is called LOW.The XNOR is opposite to XOR.The output of XNOR gate is HIGH whenever the two inputs are identical.
