An electronic circuit that produces an output signal of a specific frequency. An oscillator generally consists of an amplifier having part of its output returned to the input by means of a feedback loop; the necessary and sufficient condition for oscillation is that the signal, in passing from input to output and back to input via the feedback loop, arrive at the input with no change in amplitude or phase. If this condition is met for only a single frequency, the output is a pure sine wave; if it is met for more than one frequency, the output is a complex wave. Some oscillators are designed to operate under certain conditions so that the output is a square wave, a triangular wave, or a pulse. In some cases, a very stable mechanical oscillator, such as a specially prepared quartz crystal, may be coupled to an electronic oscillator to enhance its frequency stability.
An electrical device that uses varying voltages to oscillate at different frequencies, thereby producing musical notes.
An electronic circuit that produces a continuous output waveform with only DC applied.
A device that generates a tone at a given or selectable frequency.
Device that oscillates. Sound is the oscillation of air caused by a mechanical oscillation such as that from a moving piano string or drum head. An electronic oscillator is a device containing circuits designed to produce electrical oscillations that are maintained, usually at a constant amplitude, and may have other specific characteristics that suit them for use as circuit test signals.
1) An audio device used to generate test tones at various frequencies for test and troubleshooting applications. 2) The tone generating device in a synthesizer used to create instrument sounds.
An electrical circuit which produces simple electrical waves at given frequencies.
An electronic device which generates a periodic signal of a particular frequency, usually a sine wave, but other waveforms (square, sawtooth, triangle) are often used. Oscillators are common in audio devices such as synthesizers and test signal generators. Early synthesizers used oscillators as the basic component for all of the sounds of the machine. All of the filters and envelopes modified the sound created by the oscillator to produce the desired sound. Nowadays most keyboards produce sounds by playing back samples recorded on chips or by more modern synthesis techniques such as Physical Modeling (see DJzone archive Physical Modeling Synthesis), FM, LA, or any number of other methods that have been employed in the past 10 years.

a device that produces alternating current
A device used to produce a wave or oscillation. Oscillation means movement backwards and forwards, like a pendulum. If you move your hand backwards and forwards in water you will produce waves whose frequency depends on how fast you move your hand. One oscillation (or wave, or cycle, or Hertz) is one complete movement backwards AND forwards.

Digitally Controlled Oscillator. An analog oscillating circuit controlled and monitored by a digital microchip. This offers a very stable, accurate, self tuning analog sound in a synth which is less likely to overheat.
Voltage Controlled Oscillator. An oscillating circuit controlled by an alternating analog voltage. This creates the sound in the synthesizer using basic waveform shapes like sine, sawtooth, square, triangle and PWM. Tuning can be unstable, synths can overheat and are often very heavy.
(circuit) Any non -otating device for setting up and maintaining oscillations of a frequency determined by the physical constants of the system. A device for producing electric oscillations; specifically a radio-frequency or audio-frequency generator (especially of the non-rotating type).
The heart of modern quartz timers. The quartz crystal oscillates at a specific frequency, yielding a highly accurate timebase. The best timers employ Temperature-Compensated Crystals ( TCXO), which function accurately in extreme weather conditions.
a timing device consisting of quartz crystal and an oscillation circuit to generate an output signal at a constant specified frequency.
Technically, something that generates a repeating analog signal, like a sine, triangle, sawtooth, or square wave. Historically, those were the basis for analog synth sounds. The 01 uses OSC to mean any of the basic PCM sounds, meaning a Multi-Sound or Drum Sound. The 01 manual also uses "voice" to mean "oscillator".
An electric circuit which generates an alternating current by use of positive feedback.
An electronic sound source. In an analog synthesizer, oscillators typically produce regularly repeating fluctuations in voltage; that is, they oscillate. In a digital synth, an oscillator more typically plays back a complex waveform by reading the numbers in a wavetable.
An electronic circuit consisting of an amplifier and a phase-shift network connected in a positive feedback loop that produces a time-varying output signal without an external input signal using positive feedback. A circuit designed to produce a sinusoidal, triangular, or rectangular output. A circuit that converts dc to ac.
