An XNOR gate is another digital logic gate that outputs true (1) only when the number of true inputs is even. In other words, the output is high when the number of true inputs is equal. The XNOR gate is also known as an equivalence gate and is denoted by the symbol ⊙ or by the...
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. There are two symbols for XNOR gates: the 'professional' symbol and the 'rectangular' symbol. For more information see Logic Gate ...
The current symbol of the Equivalence gate as an Exclusive OR with the output ASSERTED LOW (Exclusive NOR) is troubling when we want to think of the output ASSERTED HIGH. This had impeded extending the mixed logic approach to Exclusive OR. We suggest introducing an alternative distinct symbol ...

TheAND gateis so named because, if 0 is called "false" and 1 is called "true," the gate acts in the same way as the logical "and" operator. The following illustration and table show the circuit symbol and logic combinations for an AND gate. (In the symbol, the input terminals are ...
