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 two-thirds 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 weeks to receive explanations of a practice. During the assigned lab sessions, the teacher will be available for the first two sessions and a monitor for the third session to answer questions and monitor the work.
- The statements of the practices will be facilitated with the corresponding model to present the results.
- 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.
- If the result of the evaluation is not favorable, a final retake exam will be presented in June and if it is not passed then there will be a last chance in July.
The final theory grade will be calculated from the two semester grades. An average will be made between the two semester grades as long as they are equivalent to or greater than 4.
Semester grades will be calculated based on the exams grade (Grade_Exams) and the continuous evaluation grade (Grade_CE) according to the following formula, provided that the exam grade (Grade_Exams) is equal to or greater than 4:
Grade_Semester = 70% · Grade_Exams + 30% · Grade_CE
If the exams grade (Grade_Exams) does not reach 4, then the semester grade will be directly the exams grade, that is, Grade_Semester = Grade_Exams.
On the other hand, the exams grade (Grade_Ex) will be calculated by weighting the grades of the mid-term exam (Grade_MidTerm) and the grade of the final semester exam (Grade_Final) according to the following formula:
Grade_Exams = 70% · Grade_Final + 30% · Grade_MidTerm
In June only the second semester will be evaluated.
The semesters will release contents from the exam until the extraordinary retake, included, provided they have a minimum grade of 4.
Students who have not passed the theory in June will have an extraordinary exam (July), in which they can take the retake exams for the semesters that they have not previously released. In these cases, the semester grade will be directly the grade of the retake 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.
The evaluation of practical knowledge has its own rules that are different from those presented previously.
To pass the subject, the theory and the practices will have to be passed independently with a minimum grade of 5 in each of them.
The final grade for the subject will be made up with 70% of the theory grade plus 30% of the practices grade once both parts have been aproved.
The student must:
- Demonstrate the necessary knowledge related to the subject.
- Be able to solve, interpret, and design any problem in the field of electronics that may arise.
- Be able to interpret the numerous pieces of information provided for the exercises, synthesizing them and choosing the best procedures to solve the problems.
- Be accustomed to working with real data from manufacturers.
- Be able to plan their tasks related to the exercises in order to submit them within the established deadlines and successfully pass the periodic tests.
- Have the organizational skills to work effectively and foster teamwork. Through this teamwork, they should be able to overcome any problem by applying the acquired knowledge.
- Maintain consistency in their work and in assimilating the content so that they acquire it progressively.
