The students attending the course for the first time will be excluded from the final exivo anterior am, if they miss more than 25% of the problem solving tutorials.
Two components are taken into account:
- Mid term test – 1mini-tests, which will not last more than 1h 30m (AD)
- Written Exam – a final exam, which will not last more than 2h 30m (CF)
The final mark for these students will be calculated by the formula CF =max(0,25 AD + 0,75 EF, EF).

Students approved in the regular final exam may have optional access to a special designed exam if they wish to raise their final mark. The classification obtained in this exam substitutes the previous one, if it is higher. Note that in this case the continuous assessment is discarded, and the classification is given by the exam alone.
Students may only achieve very high grades, namely 19 and 20 out of 20, if they obtain a compatible result in a special oral exam in the face of a jury composed by at least two members of the teaching staff.
Even though is it not written in the program and aims of the course, students should use the computer resources available. In FEUP’s network Matlab is available, a powerful computer tool. It can be used countless tools, simulators and the system of John Hopkins University.
Regular visits to the open course ware site are also stimulated, namely the signals and systems course home.
