Lecturer:

Tutor:

Supervisor:

Department of Telecommunications Engineering

Synopsis:

This subject deals with principles and methods of digital signal processing starting with analog signal discretisation, using of integral transformation (Z, FT, DFT, FFT, DCT), digital filtering and adaptive filtering, low rate speech and image coding. The accent is given on above mentioned methods and its realization by telecommunications equipment using of digital signal processors.
