'''Analog''' and [[digital]] signals are a means of representing information. An analog [[signal]] is a continuously varying signal, so called because it is analogous to the original data.<ref>[http://createdigitalmusic.com/2013/07/video-explains-why-difference-between-analog-digital-isnt-what-most-people-think/ Video Explains Why Difference Between Analog, Digital Isn’t What Most People Think] by Peter Kirn, 29 July 2013</ref>
== Electronics ==
Commonly seen as in [[transistors]] (in non-switching mode), [[RC filters]] and many other circuits.
== Synthesis ==
Analogue synthesizers use analogue [[circuit]]ry such as [[Voltage Controlled Oscillato]]rs to generate simple [[waveform]]s such as square waves and sawtooth waves and [[Voltage Controlled Filter]]s to process the waveforms. Both analogue and digital synthesizers produce an analogue waveform (as a variable voltage electrical signal) at the output.<ref>[https://en.wikipedia.org/wiki/Talk:Digital_synthesizer#Very_poorly_written_and_non_technical Very poorly written and non technical], Digital synthesizer talk page, Wikipedia</ref>
