Cíl

The aim of the course is to provide students with a coherent explanation of the basic theory of digital signal processing with an emphasis on understanding the computational algorithms used in digital processing. Especially emphasized are methods for describing digital systems, especially digital filters. The subject is closed by discussions about the implementation of DSP algorithms in microprocessors and digital signal processors.
