The methodology used in this subject separates lessons in two kinds: theoretical and practical.
Theory lessons basically consist of theoretical explanations of the subject´s contents and solving problems related to these contents. In each theory block, problems are posed for the students to resolve at home and hand in to the teacher in order to do a continuous evaluation. Some problems are also posed in class for students to resolve them in situ and actively participate in class.
Practical lessons have the intention of giving practical examples of that explained in the theoretical classes. In order to do the practical classes in the Electronics laboratory, students are divided into smaller groups with a teacher for each group. These lessons are attended and are always done with the teacher, for any advice they may need. Students do the practices in pairs.
Each one of the practices consists of various sessions. In the first sessions the teacher goes through the theoretical contents necessary to do the practices, and the assemblies which need to be done. The following sessions are for the student to simulate all the suggested assemblies with the computer and the adequate software. Once this is studied, and with a clear idea of the final design, the last sessions are for the practical assembly. This assembly and its technical report must be defended before the teacher.
For the student´s better performance he/she has the possibility of personalized consultations on the subject, at a contents level, or on any other related matter (studying methods, planning, practical designs, problems correction )
This subject is divided in two different parts: a theoretical and a practical part. Each part is evaluated separately and each one has to be passed in order to pass the complete subject.
If both parts are passed, the subject´s final grade will be the arithmetic addition of the Theoretical grade (out of 10) and the Practical grade (out of 2). If the addition of both grades is over 10, then the subject´s final grade is MH.
In the event that someone doesn´t pass the theoretical part, the subject´s global grade will be the one of the theoretical part, only if the practices have been handed in. If the student has not take the Theoretical exam or has not handed in the practices, the subject´s grade will be NP.
Theoretical part evaluation:
The theoretical grade is the result of calculating the arithmetical mean of each term´s theoretical grade, provided that both terms have been passed. If the student has failed one term, the theoretical grade is also failed automatically.
The half-yearly theoretical grade is obtained from the exams and the continuous evaluation done along the semester.
This subject has two semesters. Each one is passed provided that the grade is equal or higher than 5. Each term grade is obtained from the higher grade of:
a) GRADE_ OF_ THE_HALF-YEARLY_ EXAM x 0.7 + CONTINUOUS_EVALUATION x 0.3 (if the exam´s grade isn´t above 3.5, the term´s grade will by the same as the exam´s grade directly)
b) GRADE_OF_THE_ HALF-YEARLY_EXAM
The continuous evaluation grade of each term is obtained from the term´s practices, problems and projects made at home or in class, and from the midterm exam´s grade. The continuous evaluation grade of each term is kept for the remedial exams.
The midterm exam allows exonerating some content for the half-yearly exam (not for the remedial exams). The midterm exam grade is calculated from the midterm exam grade (70%) and the continuous evaluation done up to that moment (30%), provided that the exam grade is higher to 3.5. If it is lower than 3.5, the grade for the midterm will be directly the one of the midterm exam.
The exam for the first semester is on February.
During the June ordinary period of exams, the second semester exam must be taken, and in case that the February exam was failed, it must be retaken again in June.
In the event that one semester has a grade lower than 5, the student must retake the exam during the extraordinary period. During the recovery exams, students must take the semesters failed during the ordinary exams.
Practical part evaluation:
It is evaluated with: home works, reports and group works, practical works in the computer, presentations and participations in the laboratory.
The practices are done in pairs. They must be handed in along the course in the established deadlines. During the ordinary and extraordinary period of exams there are established due dates for delayed practices (with a penalization in the grade)
In order to pass the practical part, all the subject´s practices must be handed in. Each practice is graded between 0 and 2 points according to the quality of the previous study, the reports, the assembly and the presentation. The final practice mark is the average of the different practice grades according to a weighting. The final grade will be between 0 and 2. If a student doesn´t hand in any practice, the practical grade will be NP.
For those repeating courses, the practices´ grade will be saved only for a year. The third year it must be validated.
Objective 1
Student must prove to have the basic knowledge related to the subject
Objective 2
Students must know how to resolve and design any problem posed in the field of analog electronics
Objective 3
Students must have the capacity to plan all the tasks related to the practices in order to hand them in on the dates established for each one of the parts forming the practices.
Objective 4
Students must be used to working with the computer and to systems analysis and design on the computer, as a step previous to the implementation of any design
Objective 5
Students must have the capacity for organization in order to work and promote team work. In the same way, team work provides the possibility of developing the capacity of applying the knowledge acquired to the practical design and being able to solve any problem.
Objective 6
Students must have the capacity for synthesis in front of all the information received, in order to choose the best elements for the realization of the practices.
