A synthesizer (also spelled synthesiser) is an electronic musical instrument that generates audio signals. Synthesizers generate audio through methods including subtractive synthesis, additive synthesis, and frequency modulation synthesis.
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.
A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds. This in contrast to older analog synthesizers, which produce music using analog electronics, and samplers, which play back digital recordings of acoustic, electric, or electronic instruments.

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. produced numerous models from 1965 to 1980. It was the first commercial synthesizer, and is credited with creating the analog synthesizer as it is known today. By 1963, Moog had been designing and selling theremins for several years. He began developing the Moog synthesizer in response to demand for more practical and affordable electronic music
In the early 1960s, electronic music technology was impractical and used mainly by experimental composers to create music with little mainstream appeal. In 1963, American engineer Robert Moog, who designed and sold theremins, met composer Herb Deutsch at a New York State School Music Association trade fair. Deutsch had been making electronic music using a theremin, tape recorder, and single-pitch oscillator, a time-consuming process that involved splicing tape. Recognizing the need for more prac
The Moog synthesizer consists of separate modules – such as oscillators, amplifiers, envelope generators, filters, noise generators, ring modulators, triggers and mixers – which can be connected in a variety of ways via patch cords. The modules can also be used to control each other. The Moog does not produce sound until a workable combination of modules are connected. The synthesizer can be played using controllers including keyboards, joysticks, pedals, and ribbon controllers. The ...
The Moog was much smaller than previous synthesizers, and much cheaper, at $10,000USD compared to the six-figure sums of other synthesizers. Whereas the RCA Mark II was programmed with punchcards, Moog's synthesizer could be played in real time via keyboard, making it attractive to musicians. New Scientist described it as the first commercial synthesizer. According to the authors of Analog Days, "Though the notion of voltage control and Moog's circuit designs were not original, Moog's innovation
In 1970, Moog Music released the Minimoog, a portable, self-contained model, and the modular systems became a secondary part of Moog's business. The Minimoog has been described as the most famous and influential synthesizer in history. After the sale of Moog Music, production of Moog synthesizers stopped in the early 1980s. The patents and other rights to Moog's modular circuits expired in the 1990s. In 2002, after Robert Moog regained the rights to the Moog brand and bought the company, Moog re
An analog (or analogue) synthesizer is a synthesizer that uses analog circuits and analog signals to generate sound electronically.. The earliest analog synthesizers in the 1920s and 1930s, such as the Trautonium, were built with a variety of vacuum-tube (thermionic valve) and electro-mechanical technologies.

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-
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
Speech synthesis is the artificial production of human speech.A computer system used for this purpose is called a speech computer or speech synthesizer, and can be implemented in software or hardware products.

Een synthesizer is een elektronisch muziekinstrument dat klanken en geluiden kunstmatig (meestal elektronisch) opwekt. Met een synthesizer is het mogelijk het op te wekken geluid vergaand te beïnvloeden, zodat nieuwe, nog niet bestaande klanken gemaakt kunnen worden.
