| Summary |
|---|
| Student will be informed about special terminology and basic definitions and with kinds of disturbances. Rules and standards of EMC are also included into subject contents and also possible ways of active and passive elimination of disturbances. |
| Learning Outcomes of the Course Unit |
|---|
To inform students about electromagnetic disturbance and with possible ways of its elimination.
After subject graduation the student will be able to identify, outline and decode disturbing influences in electrical networks and to interprete measured results in relation to valid standards and rules including of solving finding for disturbance elimination and their comparing. |
