In telecommunications, modems perform signal modulation and demodulation processes to encode information from digital devices onto signals carried by analog circuits. Digital Service Units (DSUs) and various other devices modulate carrier waves to place digital signals on digital circuits. See also AM, FM, modem, PM, and PSK.

In telecommunications, codecs code analog signals into digital format prior to transmission over a digital circuit, and decode them on the receiving end of the connection. Codecs use a variety of modulation techniques, including adaptive differential pulse code modulation (ADPCM), differential pulse code modulation (DPCM), and pulse code modulation (PCM). See also ADPCM, analog, codec, digital, DPCM, and PCM.
