The introductory subject to the study of Digital Signal Processing. The main emphasis is focused on the interpretation and acquirement of the basic principals. Practical approaches and real examples from different areas (music, biomedical engineering, speech processing communication systems) are used.
The program system MATLAB is used for the tasks solution, which offers comfortable and user friendly environment with graphical and sound outputs and allows digital signal processing in different formats.

The condition for granting credit is elaboration of selected task in MATLAB.

The aim of the study is theoretical and practical knowledge in the fundamentals of digital signal processing.
