trigger circuit
  • A circuit which serves as a trigger (1), trigger (2), trigger (3), or trigger (4).
  • A two-stage multivibrator circuit with two stable states. In one of the stable states, the first stage conducts while the other is cut off, while in the other state the reverse is true. When the appropriate input signal is applied, the circuit flips from one state to the other. It remains in this state until the next appropriate signal arrives, at which time it flops back. Used extensively in computers and counting devices. Also known as bistable multivibrator, flip-flop circuit, flip-flop, Eccles-Jordan circuit, bistable flip-flop.
  • A circuit whose output changes drastically in response to a minimal change in its input.
