Teaching methodology

There will be a complementation between classes of theory and problems, lectures are reinforced with examples showing the possible alternatives and solutions to common problems. Some topics will be proposed for self-assessment exercises that students can be aware of your progress, and may ask teacher support in case it detects any deficiency. The practical sessions will take place in situ in the laboratory teaching department in the FIB. There will be two practices that require large cumulative work of students in the preparation of a project.

Evaluation methodology


The grade for this course will be obtained from the weighted average of the marks of theory (40%), laboratory practices (40%) and final work (20%)

NF = 0.1 CT1 + 0.1 CT2 + 0.1 CT3 + 0.1 CT4 + 0.40 PL + 0.2 TF (CT = control theory, PL = Laboratory, TF = Final Work)

The laboratory mark (PL) will be obtained while doing practical work in the lab. There will be at least two partial deliveries of the practices.

In addition students must deliver a design of an embedded system based on a real problem. This work will be presented at the end of the course and will produce the mark TF. The docs for this design will be written in English. The quality of design, the selection of components and clarity of the presentation will be evaluated.

With the report in english and the presentation of the final work a grade for the Cross-Competence (G3.2) will be obtained.
