Astable multivibrator, in which the circuit is not stable in either state —it continually switches from one state to the other. ... Monostable multivibrator, 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.

What is the output of astable multivibrator?

The basic transistor circuit for an Astable Multivibrator produces a square wave output from a pair of grounded emitter cross-coupled transistors. Both transistors either NPN or PNP, in the multivibrator are biased for linear operation and are operated as Common Emitter Amplifiers with 100% positive feedback.

Which IC is used in the astable multivibrator?

Astable multivibrator using 555 IC is a simple oscillator circuit that generates continuous pulses.
