Multivibrator Circuit. The astable circuit consists of two switching transistors a cross coupled feedback network and two time delay capacitors which allows oscillation between the two states with no external triggering to produce the change in state. The output of the 2 nd stage is then through a feedback path is provided to the input of the 1 st stage.

It generates non sinusoidal waves such as square waves rectangular waves and saw tooth waves etc. Astable multivibrators generally have an even 50 duty cycle that is that 50 of the cycle time the output is high and the remaining 50 of the cycle time the output is off. Multi vibrator circuits refer to the special type of electronic circuits used for generating pulse signals.
A multivibrator is an electronic circuit used to implement a variety of simple two state systems such as light emitting diodes timers and flip flops.
It can blink just one led. Here two amplifiers are employed in which the output from the 1 st stage acts as input to the 2 nd stage. It doesn t have to flash two leds though. Basics of multivibrator the multivibrator is a switching circuit and its basic configuration is shown below.
