The methodology used in this subject distinguishes two types of lessons: theoretical and practical.
This course is provided in presential and semi-presential modes. In the first case, theory lessons basically consist of theoretical explanations (sometimes combined with slides) whereas, in the semi-presential mode, the student must follow a guide of study through on-line sessions.
In the presential theoretical sessions, the contents of the course are explained and complementary some problems related to these contents are posed and solved. In each theory block , typical exam problems with their solutions are posed for the students, so they can be familiarized with the theoretical contents through practical problems.
In the semi-presential mode, the student must follow a guide of study structured in sessions. For each session there is an introduction, related literature and a set of exercises for self-assessment. The student can solve their questions by different means: scheduled presential support from the professor, virtual forums, e-mail, news and supporting literature available in the intranet (called E-campus).
For practical lessons, students are divided into smaller groups with a teacher for each group. They can choose their practical session timetable among the available options. In order to perform the practical session in the television laboratory, students are divided into groups of three people. Each group has a table with all the equipment necessary to make the practical work. Every student must compulsory assist to these sessions. During the practical sessions, students measure and analyse the parameters of the television systems and signals with the teacher near them to help them with their doubts.
Before the realization of the practical work, the professor explains the theoretical concepts that are needed for the session. He also shows how the equipment operation should be done in order to perform the measures and analysis that are required for the practical work. Moreover, the students also have the user manual of the equipment to complement the explanations. In case of lack of time to perform the practical work within the practical session, the students can also finish the measures when the laboratory is free of any other practical session.
The groups of three people that are constituted at the beginning of the course to make all the practical works can not be changed during all the course. Therefore, the group reports of the each practical work will count as a percentage of the final mark. With this we guarantee a positive interdependence between the members of the group.
The subject is divided in two clearly different parts: the theoretical and the practical. Each one of these parts is evaluated separately and it must be passed independently to the other one in order to pass the subject.
If both parts are passed, the final mark is the result of the assessment of 75% for the Theory mark and a 25% for the Practices mark. In case of failing the theoretical part, the subject´s global mark is the Theory mark, if the practices have been passed. In the case of not attending one of the two parts (theory or practice) the subject´s mark is NP (Not Presented).
Evaluation of the theory part:
A. Exams
The mark for the theory part is obtained from final course exam. The exams consist on problem solving (60%) and theoretical questions (40%). There are two opportunities to pass the exam with a note equal or superior to 5.
Evaluation of the practical part:
A. Exams
D. Homework
F. Team reports
G. Computer assignments
K. Laboratory reports
L. Laboratory participation
To pass the practical part the following requirements must be fulfilled:
- The presence to the practical sessions is obligatory. If the student cannot assist to a session he must retrieve it another day when the laboratory is free of any other practical session.
- Each group must write a laboratory report with the computer for each practical work, with the solution to each section of the practice.
- The reports must be handed in during the course on the established dates.
- At the end of the course there is an exam of all the practical sessions. This is an individual exam and must be passed, independently of the reports, to pass the practical part.
The practical final mark is a 50% for the reports mark and another 50% for the practical exam.
