"a synthesizer that uses analog circuits and analog computer techniques to generate sound electronically."
(Analogue electronics (or analog in American English) are electronic systems with a continuously variable signal, in contrast to digital electronicswhere signals usually take only two different levels. The term "analogue" describes the proportional relationship between a signal and a voltage or current that represents the signal. An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved.)
These devices came into use as early as the 1920s. The first analog synthesizers were built with " vacuum-tube (thermionic valve) and electro-mechanical technologies." As technology advanced, the analog synthesizers were updated with the use of "operational amplifier (op-amp) integrated circuits and potentiometer (pot, or variable resistor)". By the 1980s, digital synthesizers had replaced analog synth but the analog did experience a resurgence within the techo wave of the 1990s. "The demand for the analog synth sound led to the development of a variety of analog modeling synthesizers which emulate analog VCOs and VCFsusing samples, software, or specialized digital circuitry, and the construction of new analog keyboard synths".
