One-Shot Terminology — Alternate Name In pulse generation and timing circuits, a “one-shot” is commonly referred to by which formal multivibrator classification?

Introduction / Context:
Multivibrators are fundamental timing circuits classified by the number of stable states. The term “one-shot” is widely used in practical electronics to describe a circuit that produces a single pulse of fixed duration in response to a trigger.

Given Data / Assumptions:

• The device generates one pulse per trigger and then returns to its resting state.
• It is not free-running; it requires an external trigger.
• Classic implementations include 555 timers and monostable logic configurations.

Concept / Approach:
A monostable multivibrator has one stable state and one quasi-stable state. When triggered, it temporarily switches to the quasi-stable state for a duration set by R and C, then returns to the stable state, hence “one-shot.”

Step-by-Step Solution:
Define stable states: monostable → one stable, bistable → two stable, astable → none stable (free-running).Match behavior: a single output pulse per trigger corresponds to a monostable.Conclude that “one-shot” equals “monostable.”

Verification / Alternative check:
555 monostable application notes describe the same behavior and explicitly use “one-shot” and “monostable” interchangeably.

Why Other Options Are Wrong:

• Multivibrator: Generic class name; not specific.
• Bistable: Two stable states (flip-flop), not a one-shot pulse.
• Astable: Free-running oscillator with no trigger required.

Common Pitfalls:
Confusing monostable with astable due to similar RC timing formulas; remembering that astable oscillates continuously while monostable needs a trigger.

Final Answer:
Monostable
