A multivibrator is an digital circuit that generates pulse alerts or square waves through switching among different states. The Multivibrator Definition classifies it into three types: Astable, which oscillates continuously; Monostable, which requires an outside trigger; and Bistable, which remains in considered one of solid states till triggered. Multivibrators are extensively used in timing circuits, waveform era, and digital electronics.
Definition of a Multivibrator
Types of Multivibrators
The Multivibrator Definition refers to an digital circuit that switches among different states to generate pulse signals. According to the Multivibrator Definition, those circuits are categorised into three essential kinds primarily based on their balance. Understanding the Multivibrator Definition is important for packages in electronics and virtual systems.
- Astable Multivibrator – Has no strong state and constantly oscillates among high and low states.
- Monostable Multivibrator – Has one stable nation and switches to an volatile kingdom whilst induced.
- Bistable Multivibrator – Has two solid states and modifications state while an external trigger is applied.

Astable Multivibrator: Working and Applications
An Astable Multivibrator is an digital circuit that has no solid state and continuously oscillates between high and coffee voltage ranges. It is likewise referred to as a unfastened-going for walks oscillator as it does no longer require any external trigger to change states. The circuit usually includes transistors, resistors, and capacitors that create a self-maintaining switching motion.
- When one transistor turns ON, the other turns OFF due to the capacitor’s charging and discharging.
- The capacitor linked to the bottom of the OFF transistor starts charging, in the end turning it ON even as the primary transistor turns OFF.
- This manner repeats constantly, generating a square wave output sign.
- The frequency of oscillation depends on the values of the resistors and capacitors used within the circuit.
