VCOs can be generally categorized into two groups based on the type of waveform produced. [4]Linear or harmonic oscillators generate a sinusoidal waveform. Harmonic oscillators in electronics usually consist of a resonator with an amplifier that replaces the resonator losses (to prevent the amplitude from decaying) and isolates the resonator from the output (so the load does not affect the ...
With the advent of polyphony, tuning problems became worse and costs went up, due to the much larger number of oscillators involved (often 16 in an 8-voice instrument like the Yamaha CS-80 [3] from 1977 or Roland Jupiter-8 [4] from 1981). This created a need for a cheap, reliable, and stable oscillator design.
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The (instantaneous) frequency of an oscillator is altered in accordance with the amplitude of a modulating signal.

Oscillator sync is a feature in some synthesizers with two or more VCOs, DCOs, or "virtual" oscillators.As one oscillator finishes a cycle, it resets the period of another oscillator, forcing the latter to have the same base frequency.
RC oscillators are a type of feedback oscillator; they consist of an amplifying device, a transistor, vacuum tube, or op-amp, with some of its output energy fed back into its input through a network of resistors and capacitors, an RC network, to achieve positive feedback, causing it to generate an oscillating sinusoidal voltage.
Infrared optical parametric oscillator. An optical parametric oscillator (OPO) is a parametric oscillator that oscillates at optical frequencies. It converts an input laser wave (called "pump") with frequency into two output waves of lower frequency (,) by means of second-order nonlinear optical interaction.
Schematic diagram of additive synthesis. The inputs to the oscillators are frequencies and amplitudes .. Harmonic additive synthesis is closely related to the concept of a Fourier series which is a way of expressing a periodic function as the sum of sinusoidal functions with frequencies equal to integer multiples of a common fundamental frequency.
