Four-month course , with the following schedule distribution and methodology in each case:
- 33 expositive hours distributed at three or four hours per week, given as a lecture with the support of blackboard, slides and video projector.
- 4 hours of seminars iterative solving exercises and problems
- 2 hours of tutoring in small groups spread over weeks of interactive teaching.
- 12 hours laboratory practices developed in electrical engineering and computer room where the methodology is as follows: brief explanation of the work development and implementation of practice by the student.
- Support for teaching through virtual campus with the completion of theory test which will verify the correct learning of the subject and will help improve the grade of the final exam of theory, as well as different content and agenda, transparencies, practice schedules, ...
Assessment consists of 3 sections:
a.) Evaluation of practices (10% of the final mark). The practices will be evaluated through submission of a final report, taking 10% of weight on the final qualification of the matter. The practical sessions are obligatory attendance.
b) Exercises and solving theoretical questions in the classroom (20% of the final mark).
Small exercises and tests of theoretical issues will be raised on several occasions throughout the course. These tests may be made at the end of any presential session without prior notice, or you may be notified one day in advance.
c) Final and partial exams (70% of the final mark). A final exam and an optional partial will be performed. The exams will consist of a part of theory and other exercises. (20-30 % theory, 70-80 % exercises) being required to achieve at least 25% of the score of each exercise to pass the exam. The partial exam will count 35% of the final mark, and the final examination of the ordinary call will count 35% of the approved status. In this case, only non evaluated mater will be evaluated in the final examination . People who do not wish to make the partial examination, or who do not overcome, will take the final exam of the whole subject, and in this case the value of 70% of the final mark. The minimum final exam mark will be 4 out of 10.
Sections a (final report) and b are not obligatory. Subject can be overcome if 50% of the final mark (the total of the three sections ) in the final examination is reached.
For the extraordinary call will be on the same conditions as for the ordinary call.
Repeaters students may attend theoretical classes and problems at their discretion. In addition, they may submit to all examinations and tests carried out for students of first registration.
The practices will be valid for two academic years from its completion, so it will not repeat in this period.
