A Voltage Controlled Oscillator (VCO) using 555 timer is an oscillator whose output frequency is directly dependent on the input control voltage. VCOs are widely used in communication systems, tone generators, frequency modulation (FM), and various signal processing applications. One of the simplest and most economical ways to build a VCO is by using the […]
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 […]
