Vesa Lehtinen, Mikko Valkama

Implementations

  Lecture times and places Target group recommended to
Implementation 1


Per 1, 2 :
Monday 14 - 17, TC161
Per 3 :
Wednesday 8 - 11, TB220

 
 


Requirements

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 works 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.
Completion parts must belong to the same implementation
