Astable Multivibrator Circuit Diagram, Working and Applications

An Astable Multivibrator is an essential oscillator circuit in electronics, used to generate continuous square wave signals without any external triggering. It is called “astable” because it has no stable state — both transistors in the circuit keep switching ON and OFF alternately, producing a continuous flip-flop output. In this article, we will explore a […]
