Analogue and Digital Signals


Analogue Signals

  • These vary in frequency, amplitude or both.
  • The quality of analogue signals deteriorates, especially over long distances.
  • To solve this problem, the signal is amplified every so often, but this also amplifies the background noise.
  • The quality doesn't get any better.

Digital Signals

  • A digital signal…




Thanks ! Its very useful because you're comparing the two, helpful for pros and cons. =]
