    Voltage-controlled oscillator - Wikipedia

    https://en.wikipedia.org/wiki/Voltage-controlled_oscillator

    A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for frequency modulation (FM) or phase modulation (PM) by

  3. Electronic oscillator - Wikipedia

    https://en.wikipedia.org/wiki/Electronic_oscillator

    An oscillator can be designed so that the oscillation frequency can be varied over some range by an input voltage or current. These voltage controlled oscillators are widely used in phase-locked loops, in which the oscillator's frequency can be locked to the frequency of another oscillator. These are ubiquitous in modern communications circuits, used in filters, modulators, demodulators, and forming the basis of frequency synthesizercircuits which are used to tune radios and televi…
