Moog Synthesizers
The Moog synthesizer is a modular synthesizer developed by the American engineer Robert Moog. Moog debuted it in 1964, and Moog's company R. A. Moog Co. (later known as Moog Music) produced numerous models from 1965 to 1981, and again from 2014. It was the first commercial synthesizer, and is credited with creating the analog synthesizer as it is known today. The Moog synthesizer consists of separate modules which create and shape sounds, which are connected via patch cords. Modules include voltage-controlled oscillators, amplifiers, filters, envelope generators, noise generators, ring modulators, triggers, and mixers. The synthesizer can be played using controllers including keyboards, joysticks, pedals, and ribbon controllers, or controlled with sequencers. Its oscillators can produce waveforms of different timbres, which can be modulated and filtered to shape their sounds (subtractive synthesis). By 1963, Robert Moog had been designing and selling theremins for several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltage-controlled Oscillator
A microwave (12–18GHz) 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 applying a modulating signal to the control input. A VCO is also an integral part of a phase-locked loop. VCOs are used in synthesizers to generate a waveform whose pitch can be adjusted by a voltage determined by a musical keyboard or other input. A voltage-to-frequency converter (VFC) is a special type of VCO designed to be very linear in frequency control over a wide range of input control voltages. Types VCOs can be generally categorized into two groups based on the type of waveform produced. * ''Linear'' or '' harmonic oscillators'' generate a sinusoidal waveform. Harmonic oscillators in electronics usually consist of a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
