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 […]
