Basic Electronics

This subject aims to give the student an introduction to electronic circuit analysis. Firstly, they see the basic foundations of electronics and the techniques necessary for the analysis of circuits in DC. After that, the basic electronic components (linear and non-linear resistors, capacitors and coils) are studied and the necessary knowledge is transmitted to perform the analysis of circuits in AC. Finally, other main electronic components are seen (diodes, transistors, ...) both ideal and real, linking these studies to updated documentation of different manufacturers. From a practical point of view, weekly practices are carried out in order to obtain the knowledge of the basic electronic instrumentation and to implement several circuits, which help the student to deepen in all those aspects that have been presented from the theoretical point of view and allow them to see their application.

The subject has a weekly operation with four lecture sessions for the theory and three lecture sessions for laboratory practices:
• In theory sessions, a third of the time will be devoted to lectures and the rest of the time will be done individual, team and evaluation classes taking advantage of new learning methodologies and ICT technologies.
• The objective of the learning system is to update the subject, develop a good working method and therefore a continuous evaluation system will be followed which will also allow the teacher to follow and accompany the learning of the student the personalized as possible.

Practical laboratory sessions
The practical sessions are lectures that are part of the subject and that have a biweekly regularity lecture during the course development. The purpose of these is to support and promote the necessary and essential progressive learning in order to successfully complete both the practice of the subject and a large part of the contents of the subject.
The operation of the same is described below:
• The class group will attend a face-to-face session (3 hours) approximately every 2 week to receive explanations of a practice
• The statements of the practices will be facilitated with the corresponding model to present the report of each one.
• The presentation of the practice report will take place at the end of the third session and will be individual
• At the end of each semester a written test will be carried out to demonstrate that the results of the proposed learning have been achieved.
• During the assigned laboratory sessions, monitors will be available to solve the doubts and to monitor the work.
• There will be 2 semester examinations.
• If the result of the evaluation is not favorable, a final recovery exam will be presented in June and if it is not exceeded, there will be a last chance during July.



Objective of the Continuous Evaluation

- The main goal is to help students to update the different subjects and achieve a good working method, so that it helps them to assimilate the matter imparted progressively and to obtain good academic results.
- It also allows us to assess the work the student does on a daily basis, without his note depending solely on the exams carried out during the semesters of the academic year.
- Facing the teacher, it helps to have more information about the work done by the students and a better knowledge of them, both academic and personal.

Continuous Evaluation System

- The continuous evaluation note will be determined taking into account some of the following concepts:
 Results of controls and / or small tests that are done in class, in the laboratory or through eStudy.
 Delivery of proposed exercises to do in class and / or in the laboratory.
 Delivery of exercises proposed to do at home.
 Attitude and participation in class or in the laboratory.
 Participation in eStudy forums and activities.
 Attendance at classes.

- The knowledge required in previous controls and exercises will be based on the explanations made in class or the laboratory and in the material provided to the students.

- The teacher will evaluate the student with a minimum frequency of two weeks.

- The mark will provide 70% of the knowledge reflected in the controls, exercises delivered, etc., and the remaining 30% according to the teacher's criteria (interest, attitude, dedication ...). It is always necessary to guarantee a minimum grade of 5 for students who meet the requirements for the delivery of all the exercises, jobs and controls requested by the teachers, and regular attendance at the classes.

- Two times per semester the continuous evaluation note will be published (half of the semester, to be used as an orientation and, finally, the final semester), consisting of a numerical score of 10.

- Attendance at classes is a fundamental element to be able to follow the continuous evaluation correctly.


Global evaluation System

- The final grade of theory will be calculated from the two semester notes.
- The notes of the semesters will be calculated by weighting two notes: the exam mark (Note_Ex) and the continuous evaluation note (Note_AC) according to the following formula:

Note_Semester = 70% · Note_Ex + 30% · Note_AC

Only if grade Note_Ex is greater than or equal to 3.5.

- On the other hand, the exam grades will be calculated by weighting with the semester exam notes or Control Point (Ex_control_point) and the final exam of the semester (Ex_final) according to the following calculation:

Note_Ex = 70% · Ex_final + 30% · Ex_control_point

- The semesters will release contents from the exam until the extraordinary call, provided they have a minimum grade of Four (4).
- In June only the second half of the second semester will be evaluated.
- Students who do not pass the June ordinary session will have an extraordinary call (July), in which they can carry out the recovery examinations of the semesters that have not been previously released. At the extraordinary call, the final grade of each semester will be the best of those obtained with the following calculations:
a) 70% of the recovery exam and 30% of the continuous evaluation obtained in the corresponding semester (only if the mark of the recovery exam is greater than or equal to 3.5).
b) 100% of the recovery exam.

- The evaluation of the theoretical knowledge and the practical knowledge will be independent, it is not mandatory to pass one of the parts to present to the other one. Attendance to practical classes and the presentation during the course of these can be considered as information for the continuous assessment note.
- To approve the subject, the theory and practices will have to be approved independently.
- The calculation of the final mark of the subject will be done with 70% of the theory mark plus 30% of the practical note.
