Teaching languages


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 achieve a basic understanding of spoken Catalan. However, exams and practical reports can be written in Italian or other languages. Public questions in the classroom, and private questions to the lecturer, can also be posed in Italian or other languages.

Skills


Specific skills
  • EC11: Knowledge of the fundamentals of electronics.

Description


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.

In later subjects other blocks and other components will be studied.

Learning outcomes


In general, this subject contributes to the following learning outcomes specified by the subject to which it belongs:

- Know, understand and use the principles of electronic components and systems.

- Carry out measurements in electrical systems and electronic circuits.

- Write texts with the appropriate structure for communication objectives. Present the text to an audience with the appropriate strategies and means.

- Know and put into practice the way and dynamics of teamwork.

- Identify one's own information needs and use the collections, spaces and services available to design and carry out searches appropriate to the subject area.

- Carry out the assignments based on the basic guidelines given by the teacher, deciding the time to be used in each section, including personal contributions and expanding the sources of information indicated.

- Know a third language with an adequate level, both orally and in writing.

At a more specific level, at the end of the course the student must be able to:

- Identify the blocks of a general electronic system, and explain the function of each of them.

- Relate the properties of a semiconductor device to its structure and composition.

- Analyze and design simple circuits with diodes and transistors.

- Calculate parameters of amplifier circuits.

- Select the appropriate amplifier circuit for each application.

Working methodology


The course consists of three hours a week of face-to-face classes in the classroom and two fortnightly hours of laboratory practice.

In the classroom, the presentation of the theoretical concepts, the resolution of exercises and examples of application by the teacher will be alternated, and occasionally, the collaborative resolution and presentation on the board of some exercise by the students. students.

In the laboratory the students, in groups of two or three, will carry out experiments related to the contents of the subject.

Students will have to devote additional time, non-contact, to the resolution of exercises, preparation of reports of laboratory practices and preparation of written tests.

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 resit exam may be used to pass the subject with a final grade of 5, but not to obtain a grade higher than 5.

In the event that the health regulations prevent a first face-to-face examination, the weighting of the evaluable activities will be:

Face-to-face final test: 70%

Laboratory practices: 30%
