“Analog media” are defined as information carriers whose universe of depictable signs is unlimited, which is why the underlying mapping rule can assume a continuous form, in the sense that a unambiguous assignment of each element of an original set to an element of the set of symbols is possible. This is particularly the case with analogue media, which are based on a continuous signal.
Examples of analogue media are the font-based media (signs, letters, leaflets), print media (book, newspaper, magazine), broadcast media (radio, television), telegraph, telex, telephone, telefax, records, audio cassette, film, photography, video, traffic signs.
