Course detail

Signals 2

FEKT-BPC-SI2Acad. year: 2021/2022

The subject is focused on the analysis and digital processing of signals from the field of telecommunication. It provides a theoretical basis of signal modulation, discrete linear transformations, description of random process and its characteristics. It also deals with the problems of filtration (FIR, IIR, adaptive, inverse), correlation and spectral analysis of signals, detection of signals in noise. The subject provides both theoretical background and practical verification. To this end, the Matlab programming environment will be used.
