He or she is able to design (3) filtering, isolation and suppression of Emi signals. The graduate is able to use (4) techniques for EMI reduction, EMC filtering, EM shielding, shielding effectiveness, magnetic shielding and cable shield. The graduate is able to (5) provide EMI measurements, EMS testing and used methods and instruments according to EMC standards and regulations, international, national and military standards. 

Prerequisites

The subject knowledge on the secondary school level is required. 

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods include lectures, practical laboratories and and an excursion to the professional workplace. 

Assesment methods and criteria linked to learning outcomes

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.
