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...
The logic symbol of XNOR gate is shown in figure 1. Fig. 1 XNOR gate truth table TheXNOR gate truth tablefor figure 1 is shown below. From XNOR gate truth table, it can be concluded that the output will be true (logical 1 or high) when all of its inputs are true or when all o...
" 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 at left and the output terminal is at right.) The output is "true" when both in...
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 ...
This had impeded extending the mixed logic approach to Exclusive OR. We suggest introducing an alternative distinct symbol for the Equivalence (Inclusive-AND) gate to facilitate the application of the mixed logic concepts to both the Exclusive-OR and the Inclusive-AND gates....
