- Syllabus of tutorials:
The practical laboratories reflect theoretical knowledge of lectures. The outline is similar to the outline of lectures.
- Study Objective:
The goal of the subject is to introduce students to basics of signals, their processing and manipulation in time and frequency domain the subjects focuses on Fourier analysis. The second part of the subject is dedicated to basics of systems, their description and features.
