Answer :

Definition:- A multivibrator is an electronic circuit that switches rapidly by means of positive feedback between two or more states. 

OR 

A multivibrator is an electronic circuit used to implement a variety of simple two-state systems such as oscillators, timers and flip-flops.


Types of multivibrator

There are three types of multivibrator circuit depending on the circuit operation: 

Astable, in which the circuit is not stable in either state —it continually switches from one state to the other. It does not require an input such as a clock pulse. 

Monostable, in which one of the states is stable, but the other state is unstable (transient). A trigger causes the circuit to enter the unstable state. After entering the unstable state, the circuit will return to the stable state after a set time. Such a circuit is useful for creating a timing period of fixed duration in response to some external event. This circuit is also known as a one shot. 

Bistable, in which the circuit is stable in either state. The circuit can be flipped from one state to the other by an external event or trigger. The bistable multivibrator is simply a latch (flip-flop)
