EMC - ElectroMagnetic Compatibility - means that electrical equipment must be able to function as intended without interfering or being interfered by its environment. The minimum requirement is defined by the legislation. Knowledge within this area is essential for everyone that will be active as a designer of electronic systems. The course is intended to give the students a fundamental understanding of how electromagnetic noise is generated and how it affects electronic systems and how it can be reduced to avoid malfunction of the systems. An overview is also given of the standards and directives that are mandatory to be fulfilled by electronic equipment.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: For grade 3: Passed compulsory parts: Lab exercises including written reports, Project including oral presentation and written report and a short written examination (2 hours). For grade 4 or 5: Larger examination that may be written or oral (5 hours).

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
