Objective of the course – aims of the course unit:|
The aim of the course is to provide comprehensive explanation of the basic theory of digital signal processing, with emphasis on applications in microprocessor technology. Extra emphasis is laid on methods of spectral analysis and digital linear and non-linear filtering. The course is concluded with a discussion of quantizing effects and of the realization of algorithms in microprocessors and digital signal processors.
Objective of the course – learning outcomes and competences:|
The student will have a good grasp of algorithms for digital signal processing, s/he will be able to apply them and model them by means of the MATLAB program. S/he will be knowledgeable regarding algorithm realization on microprocessors and digital signal processors, inclusive of all the problems involved in the realization.
The subject knowledge on the secondary school level is required.
