These changes in voltage are applied to the voltage-controlled oscillator and the filter.

Early synthesizers were analog - they used voltage-controlled oscillators to produce sound.

At the centre of this system is a voltage-controlled oscillator, which issues step commands the phase excitation circuit.

The name is an analogy with "voltage-controlled oscillator".

In a voltage-controlled oscillator, a voltage input controls the resonant frequency.

The use of a voltage-controlled oscillator allows for consideration of different carrier frequencies.

It is a monophonic synthesizer, featuring 1 variable waveshape voltage-controlled oscillator.

They are commonly used in voltage-controlled oscillators, parametric amplifiers, and frequency multipiers.

The voltage-controlled oscillator in most phase-locked loops is built from a ring oscillator.

The Liberation featured two monophonic voltage-controlled oscillators and a polyphonic section that could play organ sounds.

Voltage-controlled oscillator, an electronic device.

Voltage-to-Frequency converters are voltage-controlled oscillators, with a highly linear relation between applied voltage and frequency.

Many voltage-controlled oscillators for electronic music are based on a capacitor charging linearly in an op-amp integrator configuration.

Voltage-controlled oscillators (VCOs) and digital oscillators may be used.

Voltage-controlled oscillators have many applications such as frequency modulation for FM transmitters and phase-locked loops.

The internal synthesizer features one voltage-controlled oscillator with simultaneous saw, square/pulse-width and sub-octave square waveforms.

The error signal is then low pass filtered and used to drive a voltage-controlled oscillator (VCO) which creates an output frequency.

In a modern-day voltage-controlled oscillator an injection-locking signal may override its low-frequency control voltage, resulting in loss of control.

Five of these (three voltage-controlled oscillators with switchable waveforms, a noise generator, and an external line input) pass to a mixer with independent level controls.

Voltage-controlled oscillator (VCO)

A portion of the input signal spectrum is down-converted (using a voltage-controlled oscillator and a mixer) to the center frequency of a band-pass filter.

Some of designs of electronic security tag readers used in retail outlets require these high capacitance varicaps in their voltage-controlled oscillators.

Marc's style is eclectic using low frequency sound exploration, sprechgesang vocals, field recordings, water, voltage-controlled oscillators, and scordatura notation.

The signal generators (the 3 VCO's or Voltage-controlled oscillator and pink or white noise)

The voltage on the capacitor is used to tune a voltage-controlled oscillator (VCO), generating the desired output signal frequency.
