Teaching method
The course has a theoretical component of 2 hours/week and a practical component of 2 hours/week. The basic concepts and techniques are explained in the theoretical lectures. In practical classes students solve several problems by applying the techniques acquired in lectures. They also study various digital transmission systems to understand the different underlying options.
The assessment consists of 4 tests distributed over the semester or, alternatively, a final exam. A practical assessment is also done concerning the detailed study of a specific system and/or transmission technique, which can have a maximum weight of 25% on the final grade.
