The formal displacement of the geocentric principle far from being Copernicus' primary concern, was introduced only to resolve what seemed to him intolerable in orthodox astronomy, namely, the ' unphysical ' triplication of centric reference-points: one center from which the planet's distances were calculated, another around which planetary velocities were computed, and still a third center ( the earth ) from which the observations originated.

In the mid 20th century, a " codec " was hardware that coded analog signals into Pulse-code modulation ( PCM ) and decoded them back.

One way around this was to use a ' hybrid system ', most notably the Roland MC-8 Microcomposer, where a microprocessor-based system controls an analog synthesizer, released in 1978.

It was developed in parallel with the analog computers of the day.

As there was still an interest in analog synthesizers, and with the increase of computing power, another type of synthesizer was born-the analog modeling ( or " virtual analog ") synthesizer.

Digital video was first introduced commercially in 1986 with the Sony D-1 format, which recorded an uncompressed standard definition component video signal in digital form instead of the high-band analog forms that had been commonplace until then.

Before digital technology became widespread, for many decades, the scanned data was transmitted as analog.
