Anotation:

The course focuses on explaining basic terms used for the description and analysis of determined signals and systems (including filters) in continuous- and discrete-time. The graduate will acquire a basic overview of the issues and learn how to work with concepts, perform simple analysis of systems and signals, and interpret and discuss the results.

Study targets:

Become familiar with the basic concepts and learn how to use MATLAB for analysis and design of systems and for signal processing.
