How Astable Multivibrator Works?

The basic principle of the Astable multivibrator is a slight variation in the electrical properties or characteristics of the transistor. This difference causes one transistor turn ON fast than the other when power is applied for the first time, thereby triggering oscillations.

How can you design an astable multivibrator?

The output of the astable multivibrator circuit is a square wave that goes on indefinitely. As simple as it is, the astable multivibrator is often used as a pulse generator for delay circuits. It is designed in a way that the circuit will continue to oscillate without external triggers.

What is the function of astable multivibrator in IC 555?

Astable multivibrator using 555 IC is a simple oscillator circuit that generates continuous pulses. The frequency of the circuit can be controlled by shifting the values of resistors R1, R2 ad capacitor C1.
