'analog-suitable' originates from the combination of 'analog,' which refers to a continuous signal or system, and 'suitable,' meaning appropriate or fitting.

'analog' comes from the Greek word 'analogos,' meaning 'proportionate,' and 'suitable' from the Latin 'suitabilis,' meaning 'adaptable.'

Initially, 'analog' referred to proportional systems, and 'suitable' meant adaptable. Together, they describe compatibility with analog systems.
