A voltage controlled oscillator is an oscillator which produces oscillating signals waveforms with variable frequency.
Voltage controlled oscillator symbol.
Has very high resistance.
The figure below shows a simple voltage control oscillator using astable multivibrator.
The frequency of this waveform is varied by varying the magnitude of the input voltage.
This frequency is often used to keep track of time as in quartz wristwatches to provide a stable clock signal for digital integrated circuits and to stabilize frequencies for radio transmitters.

Voltage controlled oscillator vco from the name itself it is clear that the output instantaneous frequency of the oscillator is controlled by the input voltage it is a kind of oscillator which can produce output signal frequency over a large range few hertz hundreds of giga hertz depending on the input dc voltage given to it.
Graetz bridge double wave bridge rectifier with 4 diodes.
Consequently a vco can be used for frequency modulation fm or phase modulation pm by applying a modulating signal to the control input.
Generates voltage as a function of voltage or current of other circuit element.
