    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 1980.

    A frequency synthesizer is an electronic circuit that generates a range of frequencies from a single reference frequency. Frequency synthesizers are used in many modern devices such as radio receivers, televisions, mobile telephones, radiotelephones, walkie-talkies, CB radios, cable television converter boxes satellite receivers, and GPS systems. A frequency synthesizer may use the techniques of frequency multiplication, frequency division, direct digital synthesis, frequency mixing, and phase-l

    Three types of synthesizer can be distinguished. The first and second type are routinely found as stand-alone architecture: direct analog synthesis and the more modern direct digital synthesizer. The third type are routinely used as communication system IC building-blocks: indirect digital synthesizers including integer-N and fractional-N.

    Prior to widespread use of synthesizers, in order to pick up stations on different frequencies, radio and television receivers relied on manual tuning of a local oscillator, which used a resonant circuit composed of an inductor and capacitor, or sometimes resonant transmission lines; to determine the frequency. The receiver was adjusted to different frequencies by either a variable capacitor, or a switch which chose the proper tuned circuit for the desired channel, such as with the turret tuner

    A well-thought-out design procedure is considered to be the first significant step to a successful synthesizer project. In the system design of a frequency synthesizer, states Manassewitsch, there are as many "best" design procedures as there are experienced synthesizer designers. System analysis of a frequency synthesizer involves output frequency range, frequency increments, frequency stability, phase noise performance, switching time, and size, power consumption, and cost. James A. Crawford s

    A phase locked loop is a feedback control system. It compares the phases of two input signals and produces an error signal that is proportional to the difference between their phases. The error signal is then low pass filtered and used to drive a voltage-controlled oscillator which creates an output frequency. The output frequency is fed through a frequency divider back to the input of the system, producing a negative feedback loop. If the output frequency drifts, the phase error signal will inc

    In practice this type of frequency synthesizer cannot operate over a very wide range of frequencies, because the comparator will have a limited bandwidth and may suffer from aliasing problems. This would lead to false locking situations, or an inability to lock at all. In addition, it is hard to make a high frequency VCO that operates over a very wide range. This is due to several factors, but the primary restriction is the limited capacitance range of varactor diodes. However, in most systems w

  4. A musical synthesizer is an instrument that uses electricity to make musical sounds. They are the main instrument for making electronic music. Many synthesizers have a keyboard like that of a piano. When playing a piano keyboard, sounds are made by hitting soft hammers against strings pulled very tight.

  7. Synth-pop - Wikipedia

    Synth-pop (short for synthesizer pop; also called techno-pop) is a subgenre of new wave music that first became prominent in the late 1970s and features the synthesizer as the dominant musical instrument.

    Similarly, the synthesizer portion of a system often lack the variety of controls (sliders, faders, knobs) for synthesis parameters that are normally available on a standard keyboard synthesizer. Nevertheless, controlling a synthesizer with a guitar has some advantages over a keyboard.

  9. Korg - Wikipedia

    Korg was the first company to feature effects on a synthesizer, and the first to use a "sample + synthesis" sound design. The M1 workstation, released in 1988, sold over 250,000 units, making it the bestselling synthesizer ever at that time.

    En synthesizer (från grekiska "syn" och "thesis", en sammanslagning av ljudpåverkande moduler [1]), vardagligen synt eller synth, är ett elektroniskt musikinstrument som via analog eller digital ljudsyntes förmår skapa ett näst intill oändligt antal olika ljud.
