As the name suggests, a voltage controlled oscillator or a VCO circuit is an oscillator circuit whose output frequency can be controlled or varied through an adjustable control voltage input. This means, if the input control voltage is increased, the output frequency will increase proportionately, and vice versa.

The bias and gain pots of the voltage controlled oscillator circuit needs to be modified to achieve the ideal sine waveform. Vi could be any kind of positive voltage from +0.5 to + 15.0 V, providing an frequency range of around 1:100. Capacitor C could be any value from 1 On to 47n and the outputs possess a low distortion around about 20 kHz.

VCO circuit sample sounds. What is VCO ? voltage-controlled-oscillator or VCO is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, modulating signals applied to control input may cause frequency modulation (FM) or phase modulation …

VCO (Voltage controlled oscillator) Voltage controlled oscillator is a type of oscillator where the frequency of the output oscillations can be varied by varying the amplitude of an input voltage signal. Voltage controlled oscillators are commonly used in frequency (FM), pulse (PM) modulators and phase locked loops (PLL).
