Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

This training has two activities:
1. Theory course and exercise sessions
- Lecture in audience
- Problem solving in audience
2. Mandatory practical work consisting of laboratories.
- Assembly and measurement
- Data analysis and report writing
All the material (syllabus, course slides, exercise lists, lab books, electronic components and tutorials for the simulation program) can be found on the MoodleUCL site of the teaching unit
Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

The evaluation is based on:
- reports from the laboratories,
- a written exam,
- a personal project.
