analog systems
Non-digital technology methods
Analog systems process information through continuous physical quantities—voltage, pressure, position—rather than discrete digital values.
A vinyl record is analog: the groove's physical shape mirrors the sound wave.
Analog watches use moving hands; analog synthesizers generate sound through electrical circuits.
The term often contrasts with digital: We converted our old analog recordings to digital files.
