Requirements for completing the course
Exam and personal project work. The course can be taken either for 5 or 7 credits. In the basic version (5 cr), the scope and level of the personal project work are more narrow than in the extended (7 cr) version. NOTICE! *** 7 cr implementation is basically needed for those targeting to study transmission techniques in more details *** The exam and the project work should be done during the same academic year.
