 Synopsis:

The course focuses on explaining basic terms used for the description and analysis of determined signals and systems (including filters) in continuous and discretetime. 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.
