A multivibrator is a circuit that has two stable states. Each stable state is represented by a voltage e.g 0Volts and 5 volts. The astable variety is when the output. Multivibrator circuits are basically three types- monostable, bistable, astable. Find an examples of each circuit using BJT, logic gates and timer IC. The name mutivibrator designates a group of the circuits widely applied for switching as shift registers or temporary memories and as square.

The name mutivibrator designates a group of the circuits widely applied for switching as shift registers or temporary memories and as square were timing oscillator or clocks. These circuits are basically closed loop feedback circuits operating with the feedback.

The astable or free running multivibrator continuously switching from one state to the other and back to the first state. In other words it switches between two limits without application of an external signal.

It is a square of rectangular wave oscillator. It is also called free running relaxation oscillator.


What is Astable, monostable, bistable multivibrator

It has no stable state but only has two half stable states between which it oscillating. In this circuit none of the two transistors reach at stable state. When one transistor is Monostablee the other transistor is OFF and in this way they continuously switch to and fro at a rate depending on RC time constant in circuit. In this way it oscillates and generates pulses.

It has only one stable state. It can be switched from stable state to a quasi stable state by an external signal, it then returns to the stable state after a time delay. It is also known as single shot or one shot multivibrator.

Other names of monostable multivibrator are delay multivibrator and unimultivibrator. It can multivbrators switched to quasi stable state by an external trigger but it returns to the stable condition after delay time which is determined by the components of circuit. It supplies a single out put pulse of desired duration for every input trigger pulse. It has two stable states and can be triggered from one stable state to the other by an external signal. It is also known as flip flop multivibrator.


Multivibrator – Wikipedia

It has two stable states. It can remain in either of these two states unless an external trigger pulse switches it form one state to the other.

It has no energy storing element. Applications astable multivibrator applications of multivibrator astable multivibrator bistable multivibrator monostable multivibrator multivibrator types of multivibrator uses of multivibrators.
