Introduction 

Multivibrator is wave shaping circuit which generates non sinusoidal waves called Multivibrator.

Types of multivibrator

The three main types of multivibrator are astable, monostable, and bistable multivibrator.

States of Multivibrator

1. Stable state: A stable state is a state in which the circuit remains until an external trigger is applied.

2. Quasi-stable state

A quasi-stable state is a state that lasts for a finite period of time before changing to the other state.

3. Astable state

a state in which the circuit continuously switches back and forth between two quasi-stable states.

Classification of Multivibrator

A circuit which generates square wave on it’s own is called Astable multivibrator or free running multivibrator.

2. Monostable Multivibrator

A mulitivibrator in which one transistor is always conducting i.e. remains in ON state and the other is non conducting.

3. Bistable Multivibrator

A multivibrator in which both the states are stable is called bistable multivibrator.

Conclusion

A multivibrator is an electronic circuit that generates two alternating output states, which can be either stable or quasi-stable.
