Digitisation and Representation of Audio and Video Signals

  • Ulrich Reimers


The sources of the audio and video signals, such as microphone and camera, produce analogue signals, i.e. signals of an unlimited range of values, progressing continuously in the time domain. For digital processing the signals must be discretely sampled at regular intervals, quantised and coded. These processes are subsumed under the term ‘digitisation’ and are performed by analogue-to-digital converters (ADCs). Reconversion into analogue signals is carried out by digital-to-analogue converters (DACs).
