Analog refers to a type of signal or representation that varies continuously and can take on any value within a range, as opposed to digital, which uses discrete values. Examples of analog include: 1) vinyl records, 2) cassette tapes, 3) analog clocks, 4) thermometers with Mercury, 5) radio signals, 6) film cameras, 7) vinyl turntables, 8) analog synthesizers, 9) pressure gauges, and 10) sound waves in air. These examples illustrate how analog systems capture and represent information in a continuous form.
