The student of the subject Digital signal processing will understand basic algorithms for digital signal processing and he will be able to independently apply and model the basic functions of digital processing in Matlab. It will have a basic idea of the implementation of the algorithms on microprocessors and digital signal processors. Students will primarily term:
- Discrete signals and their description
- Discrete systems and their description
- Status of description systems
- Z -Transformation and its application in solving digital systems
- Frequency analysis of discrete signals
- Discrete system - frequency selective filter
- Discrete Fourier transformation
- Technical means of digital signal processing


Students should have basic knowledge of mathematics and physical description of the signal, which gets in the mandatory subjects in the previous study. Their graduating is not a prerequisite for registration of this subject.
