Entry knowledge

The subject knowledge on the secondary school level is required. 

Rules for evaluation and completion of the course

The subject Electromagnetic compatibility is evaluated in the following way: In order to obtain credit, it is necessary to measure 5 laboratory tasks out of 6 possible ones. Laboratory teaching is evaluated during the semester and a maximum of 12 points can be obtained for it. During the semester, one optional written test with a score of 18 points is given. The final exam consists of two parts (written and oral) and is evaluated for a total of 70 points. To successfully pass the exam, a minimum score of 35 points out of a possible 70 must be achieved.
Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course annually. 

Aims
