See also analogue transmission.
1. A modality based on graded relationships on a continuum: e.g. body language, paralinguistic cues, emotions, pictures, and photographs (regardless of whether they were produced using digital technology) rather than on discrete, recombinable elements (as in verbal language and mathematics). Analogical communication can signify infinite subtleties which seem ‘beyond words’. On the other hand, analogue modes lack the syntactic complexity or semantic precision that is achievable with digital modes (notably with verbal language).
2. A process whereby the physical properties of one medium are transferred to another in an analogous physical form. For example, in sound reproduction minute pressure differences in the air which the ear perceives as sounds are captured by the pressure-sensitive diaphragm of a microphone and converted into an electrical signal which is modulated to match them exactly.
