An electronic circuit that sends a signal only when all inputs are on
  • noun
  • Specialized
translation icon : circuito AND
  • Engineers tested the AND circuit to verify it only outputs a signal when all switches are turned on.

Examples

  • The AND circuit ensures that the door opens only when both security codes are entered correctly.

  • By connecting sensors to an AND circuit, the machine activates only under safe conditions.

  • The AND circuit requires all inputs to be high.

  • An AND circuit is fundamental in digital electronics.

  • The AND circuit ensures that the light will turn on only when both switches are flipped up.

  • The technician explained that an AND circuit activates an alarm only if all security sensors detect motion.

  • To create a reliable system, the engineers implemented an AND circuit which requires three inputs to be active for the output.

Morphology

AND + circuit

The components 'and' (a conjunction requiring multiple conditions) and 'circuit' (an electrical arrangement) combine in a fairly predictable way to mean a circuit that implements an 'and' operation — i.e., one that responds when multiple inputs are true. However, the precise technical behavior (Boolean logic / gate semantics) is specialized knowledge beyond a typical B1 learner, so the relation is only partially transparent.

Etymology

AND circuit comes from a simple image: imagine a gate with several locks that opens only when every key is turned. Each lock is like an input, so the circuit gives a signal only when all the inputs are on, and that is why it means 'only when all are present'.
