XOR Gate
Symbol of XOR gate: (a) two-input, (b) three-input
The Boolean expression of the output (Y) for a two-input XOR gate is given as follows: -
The truth table of two-input XOR gate is
The XOR logic function is associative; that is, any XOR function with more than two inputs can be realized using two-input XOR functions.
For example,
Y (A, B, C) = (A ⊕ B) ⊕ C = A ⊕ (B ⊕ C)
