Transmission systems and multimedia

Analogue and digital data were discussed in chapter 2. The transmission of digital data has a number of advantages. For example, each amplifier in the succession of amplifiers needed to boost analogue signals generates additive ‘noise’. Not only can digital impulses be noiselessly boosted by regeneration, they are also in a form which may directly stored, processed, etc., by a digital computer.
