Teaching languages

  • Catalan

This subject has been successfully enrolled by a number of foreign students, most of them from Italy. Classes are taught in Catalan and students are expected to have a basic understanding of spoken Catalan. However, exams and practical reports can be written in Spanish or English. Public questions in the classroom, and private questions to the teacher, can also be asked in Spanish or English.


Specific skills
  • CE11: Knowledge of the basics of electronics.


Introduction to Electronics, based on the general structure of an electronic system at the block level.

As an example, the amplifier block is studied, which is the most important and common in electronic systems.

The components with which electronic systems are built are also presented, studying in more detail the diodes and bipolar transistors.

This subject is based on the electrical systems subject. Other blocks and other components will be studied in later subjects.

Evaluation system

The final grade will be the weighted average of the grades of the assessable activities:

First partial test: 35%

Second partial test: 35%

Laboratory practices: 30%

Recovery exam: 70%

There will be a first partial test in the middle of the course and a second partial test at the end of the course.

For students who do not pass the assessment during the course, 30% of the internship grade will be maintained, and an overall retake exam will be held which will be worth 70% of the grade.

The make-up exam can be used to pass the subject with a final grade of 5, but not to obtain a grade higher than 5. Laboratory activities cannot be made up.
