<*logic*> (XOR, EOR) /X or, E or/ A two-input Boolean logic
function whose result is true if one input is true and the
other is false. The truth table is
A | B | A xor B
--+---+--------
F | F | F
F | T | T
T | F | T
T | T | F
The output is thus true if the inputs are not equal. If one
input is false, the other is passed unchanged whereas if one
input is true, the other is inverted.
In Boolean algebra, exclusive or is often written as a plus in
a circle: "⊕". The circle may be omitted suggesting
addition modulo two.
In digital logic, an exclusive or logic gate is drawn like
a normal inclusive or gate but with a curved line across
both inputs:

Exclusive or or exclusive disjunction is a logical operation that is true if and only if its arguments differ (one is true, the other is false).

¦ noun Electronics

1. a logical operation working on two variables that has the value one if one but not both of the variables is one.

2. (also **exclusive OR gate**) a circuit which produces an output signal when a signal is received through one and only one of its two inputs.

Exclusive or

**Exclusive or** or **exclusive disjunction** is a logical operation that is true if and only if its arguments differ (one is true, the other is false).

It is symbolized by the prefix operator **J** and by the infix operators **XOR** (, , or ), **EOR**, **EXOR**, **⊻**, **⩒**, **⩛**, **⊕**, $\nleftrightarrow$, and **≢**. The negation of XOR is the logical biconditional, which yields true if and only if the two inputs are the same.

It gains the name "exclusive or" because the meaning of "or" is ambiguous when both operands are true; the exclusive or operator *excludes* that case. This is sometimes thought of as "one or the other but not both". This could be written as "A or B, but not, A and B".

Since it is associative, it may be considered to be an *n*-ary operator which is true if and only if an odd number of arguments are true. That is, *a* XOR *b* XOR ... may be treated as XOR(*a*,*b*,...).
