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 […]
Voltage controlled oscillator circuit is an electronic oscillator circuit whose output frequency is controlled by an input voltage source. By varying the input voltage, we can change the output frequency. A voltage controlled oscillator can produce frequencies ranging from few Hertz to tens of Gigahertz. Voltage to frequency converters is used in frequency modulation FM […]
