Teaching methods
The lectures are organized as follows:
14 séances de cours
14 séances de cours
- 14 lecturing sessions (face to face, remotely, by means of podcasts or combination of these 3 modes, depending on the sanitary situation)
- 9 sessions of practical training/monitored exercices (solutions are provided later on on Moodle)
- laboratory sessions about AM and FM modulations.
Evaluation methods
About the lectures, the students are evaluated individually with respect to the particular objectives stated above. The examination is "closed books".
Laboratories are subject to individual evaluation as well oral evaluation by group.
The mark for the laboratories evaluation is computed on the basis of marks of an individual evaluation I and of a group evaluation G. If these marks are over 20, the global mark L over 6.66 for the laboratories evaluation is given by
L = a * G/20 + (6.66 – a) * I/20,
where factor a depends on the individual lab evaluation and is given by
In case of a second session the marks of the laboratories remain those obtained in the first session and cannot be changed. The laboratory work cannot be redone for the second session.

where factor a depends on the individual lab evaluation and is given by
- If I <= 5 : a = 0,
- If 5 < I <= 10 : a = 0.732 * I - 3.66,
- If I > 10 : a = 3.66.
In case of a second session the marks of the laboratories remain those obtained in the first session and cannot be changed. The laboratory work cannot be redone for the second session.
