Glossary
Analogue Video or audio analogue signals are those where the signals are directly analogous to the information that they are trying to represent. Therefore a loud sound or a bright picture is represented by a big signal wave; a quiet sound or a dark picture will be represented by a small signal wave. This contrasts with digital signals, where the information is represented by numeric information. Because digital signals never need to carry any more complex information than 1 or 0 (binary code), they are much more robust than analogue signals and suffer far less degradation during copying from tape to tape (generation losses) and suffer from less interference during transmission.
