analogue

A continuous waveform, such as that used in vinyl records, broadcast television or AM/FM radio. For example, when someone speaks into a microphone, that person's analogue sound vibrations are converted into analogue electrical signals, which are reproduced as analogue sound by a speaker. Digital sound, on the other hand, samples analogue waves, converting points on the analogue wave into X-Y points that are stored in a binary file. Analogue mobile phones use an analogue signalling method to convey information. The sound quality of these mobile phones is not as sharp as that of digital phones, but service coverage is currently broader. Analogue technologies are also used in CRT television and computer displays. These displays accept signals in analogue format.
