Working principle of RC multivibrator circuit

Working principle of RC multivibrator circuit A multivibrator (Multivibrator) is a self-excited oscillator capable of generating square waves, also known as a rectangular wave generator. It uses deep positive feedback and RC coupling to make two electronic devices alternately switch between conducting and cutoff states, producing a square wave output. In other words, the circuit’s output [...]
