exclusive or

[ik¦sklü·siv ′ȯr] (computer science) An instruction which performs the “exclusive or” operation on a bit-by-bit basis for its two operand words, usually storing the result in one of the operand locations. Abbreviated XOR. (mathematics) A logic operator which has the property that if P is a statement and Q is a statement, then P exclusive or Q is true if either but not both statements are true, false if both are true or both are false.

exclusive or

(logic)(XOR, EOR) /X or, E or/ A two-input Boolean logicfunction whose result is true if one input is true and theother is false. The truth table is

A | B | A xor B--+---+--------F | F | FF | T | TT | F | TT | T | F

The output is thus true if the inputs are not equal. If oneinput is false, the other is passed unchanged whereas if oneinput is true, the other is inverted.

In Boolean algebra, exclusive or is often written as a plus ina circle: "⊕". The circle may be omitted suggestingaddition modulo two.

In digital logic, an exclusive or logic gate is drawn likea normal inclusive or gate but with a curved line acrossboth inputs:exclusive or gate.
