Astable – A free-running multivibrator that has NO stable states but switches continuously between two states this action produces a train of square wave pulses at a fixed known frequency. ... Bistable – A flip-flop that has TWO stable states producing a single pulse either HIGH or LOW in value.

What is difference between astable and bistable?

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

What is astable monostable and bistable?

Systems for generating and processing pulses make extensive use of multivibrators; these are circuits which have two states. There are three types of multivibrator: astable (free-running), monostable (one-shot), and bistable (flip-flop).
