Definition
Noun: A logic gate or digital circuit that implements the exclusive OR (XOR) operation. It produces a true (or high) output only when its two inputs differ; that is, when one input is true and the other is false.
Usage
The term "xor circuit" is used in computer engineering and digital electronics to describe a fundamental building block for arithmetic and error-checking operations. * The design requires an xor circuit to compare the two data bits. * A basic half-adder is built using an xor circuit and an AND gate.
Advanced Usage
- In Cryptography: XOR circuits are crucial in many encryption algorithms for combining data with a key stream.
- The cipher uses a series of xor circuits for bitwise encryption.
- In Parity Generation/Checking: XOR circuits are used to generate and check parity bits for error detection.
- The system's error detection relies on a tree of xor circuits to calculate the parity bit.
Variants and Related Words
- XOR gate: A more common synonym for "xor circuit."
- Exclusive OR gate: The full name of the circuit.
- Logic gate: The general category to which an XOR circuit belongs.
- EOR gate: An alternative abbreviation (Exclusive OR).
Synonyms
- Exclusive OR gate

- EOR gate
Related Phrases
- XOR operation: The logical function performed by the circuit.
- XOR truth table: A table defining the circuit's output for all possible input combinations.
Noun
- gate for exclusive OR; a circuit in a computer that fires only if only one of its inputs fire
