Abstract
Digital systems are not new. The simple ‘on-off’ signalling techniques used by nineteenth-century telegraphers are one example of an early application of digital techniques. However, for many years development of the various applications of digital principles continued virtually independently; construction of electromechanical telephone exchanges, for example, progressed quite independently of the development of digital computing systems.
