The course Digital Communication Technology is a practical course on digital signal processing. Attention is paid to the realisation and function of fibre optic transmission systems with emphasis on applications of PCM technology, for example the transmission of voice and signals with real telephones, sound cards and CD players.
Learning objectives
- Learning physical basic principles
