what is Astable Monostable and Bistable in EEE

In the EEE department, students need to know  what is Astable Monostable and Bistable. Basically this three mode are a type of multivibrator circuit. So we can say there are three types of multivibrator circuit.

  1. Astable
  2. Monostable
  3. Bistable
  • Astable: in which the circuit is not stable in either state —it continually switches from one state to the other. It functions as a relaxation oscillator.

  • Monostable: in which one of the states is stable, but the other state is unstable (transient). A trigger pulse 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. It can be flipped from one state to the other by an external trigger pulse. This circuit is also known as a flip-flop. It can be used to store one bit of information.
