LD Didactic: COM4LAB: Digital Communication Technology

SKU: ME5.2.1 Categories: , Tag:


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.

  • PAM (S&H)
  • PAM spectrum
  • Over sampling / under sampling
  • Aliasing
  • Shannon theorem
  • Pulse code modulation (PCM)
  • Quantisation linear & non-linear
  • Compression / expansion
  • Code errors
  • Time division multiplexing (TDM)
  • Sychronisation
  • Quantisation noise
  • Difference pulse code modulation (DPCM)
  • Optical signal transmission
