or circuit
Definition
- Noun:
- A logic gate circuit in computing: An "or circuit" is a fundamental digital logic gate that produces a high output (fires) if at least one of its multiple inputs receives a high signal. It implements the logical disjunction (OR operation).
Usage Examples
- Noun:
- The processor's design requires an or circuit to combine the signals from these two sensors.
- If either input A or input B is active, the or circuit will output a logical '1'.
Advanced Usage
- In Boolean algebra, the function of an or circuit is represented as , meaning the output Q is true if A is true OR B is true.
- or circuits are basic building blocks in arithmetic logic units (ALUs) and memory decoders within a computer's central processing unit (CPU).
Variants and Related Words
- OR gate: A more common synonym for "or circuit."
- Logic gate: The general category of circuits, including AND, NOT, NAND, NOR, and XOR gates, to which the or circuit belongs.
- Disjunction: The logical operation performed by an or circuit.
Synonyms
- OR gate
- Logical OR gate
Related Phrases
- Inclusive OR: This specifies that the or circuit fires if inputs are high, distinguishing it from an "exclusive OR" (XOR) circuit, which fires only if input is high.
Noun
-
a gate circuit in a computer that fires when any of its inputs fire
