Astable Multivibrator:
- An Astable multivibrator is such a circuit that it automatically switches between the two states continuously without the application of any external pulse for its operation, i.e. it is unstable in any state.
- As this produces a continuous square wave output, it is called a free-running multivibrator.
A Monostable multivibrator has a stable state and a quasi-stable state. This has a trigger input to one transistor. So, one transistor changes its state automatically, while the other one needs a trigger input to change its state.
A Bistable multivibrator has both the two states stable. It requires two trigger pulses to be applied to change the states. Until the trigger input is given, this multivibrator cannot change its state.
A Bistable multivibrator has both the two states stable. It requires two trigger pulses to be applied to change the states. Until the trigger input is given, this multivibrator cannot change its state.

Explanation:
What is a Multivibrator?
A multivibrator is an electronic circuit that generates square wave signals. It has two stable states and can switch between these states in response to external triggering.
Types of Multivibrators:
There are three main types of multivibrators:
1. Monostable Multivibrator
2. Bistable Multivibrator
3. Astable Multivibrator
Explanation of Types:
- Monostable Multivibrator: In a monostable multivibrator, one of the output states is stable while the other is quasi-stable. It requires an external trigger to switch from the quasi-stable state to the stable state.
- Bistable Multivibrator: In a bistable multivibrator, both the output states are stable. It remains in one of the stable states until triggered to switch to the other stable state.
- Astable Multivibrator: In an astable multivibrator, both the output states are quasi-stable. The circuit continuously switches between the two states without the need for an external trigger. It acts as a free-running square wave oscillator.
Conclusion:
In the context of the given question, the type of multivibrator described where both output states are quasi-stable and the circuit acts as a free-running square wave oscillator is an astable multivibrator.
