Learning Outcomes

The objective of the course to provide an introduction to signals as well as to the systems that produce them, concentrating on linear systems. It offers basic system design knowledge (voice processing, image processing, telecommunication systems, automatic systems, robotics, etc) and it helps in understanding and modeling complicated modern systems.

General Skills

Independent work
Team work
Promoting free, creative and deductive thought
