​Abstract

​In the present article a short introduction about astable multivibrator and its use to generate the clock signals are addressed. In this oscillating method consist of two NPN transistors .when a signal is given to base, transistor goes to conduction. Here the oscillating circuit is the capacitors that are coupled with their parallel transistors. The intensity and frequency of the output can be modified by carrying the resistance and capacitance respectively. The main advantage is we have two outputs in this kind of oscillator which makes it fit for various special applications such as blinker as well as a kind of invertor circuits. The output can either be taken from either led bulb, transformer, or into other circuits that needs an oscillating frequencies such as in communication technologies.
