Learning activities and methodology
The course consists of the following elements: lectures, exercises, tutorials, and laboratories: LECTURES (2.5 ECTS) The lectures provide the students with explanation of the core material in the course. Numerous examples of signals and systems, their properties and behavior will be given using audiovisual support (slides, video, ...). In the second part of the course, the analysis and design of simple electric circuits will be discussed. In both parts, the basic objective is that students understand basic fundamentals in a qualitatively way. EXERCISES (2.5 ECTS) In these sessions, students will be encouraged to organize themselves forming small groups that will have to solve some basic problems given in advance. LABORATORIES (1 ECTS) The laboratories provide the students with hands-on experience to understand the fundamentals of signals, systems and circuits. Some basic signals processing demos and simple electric circuits will be analyzed. Students will also learn how to use of Matlab for signal processing and circuit analysis. Students must come prepared for the laboratory sessions.
