What we have learnt
- Multivibrators are circuits that produce pulsed outputs and can be classified into bistable, monostable, and astable types.
- Bistable multivibrators, or flip-flops, maintain stable states until triggered, while monostables have a stable state and a quasi-stable state.
- Astable multivibrators operate as free-running oscillators, continuously switching states and generating square wave outputs.
Key Concepts
- -- Bistable Multivibrator
- A circuit with two stable output states, which remains in either state until a trigger pulse causes a change.
- -- Monostable Multivibrator
- A circuit that has one stable state and one quasi-stable state, which returns to the stable state after a specific time when triggered.
- -- Astable Multivibrator
- A circuit that has no stable states; it continuously oscillates between its HIGH and LOW output states.
- -- Schmitt Trigger
- A variation of bistable multivibrator that provides hysteresis for input signals, improving noise immunity.
- -- Integrated Circuit (IC) Multivibrators
- Digital and linear integrated circuits that can be utilized for creating monostable and astable multivibrator configurations.
- -- Timer IC 555
- A general-purpose integrated circuit widely used for constructing monostable and astable multivibrators due to its simplicity and versatility.
