Content and learning outcomes
Course contents
Intended learning outcomes
After passing the course, the student shall be able to
- compute the harmonics resulting from different modulation schemes and its impact on different connected loads and sources
- solve problems related to the selection and adaptation of pulse-width modulation schemes to meet common performance criteria
- analyze modulation schemes using modern numeric computer tools and EMT simulators and explain their solutions.

Examination and completion
Grading scale
A, B, C, D, E, FX, F
Examination
- LAB1 - Laboratory Work, 1.0 credits, grading scale: P, F
- PROA - Project, 1.0 credits, grading scale: P, F
- PROB - Project, 1.0 credits, grading scale: P, F
- TENA - Written Exam, 3.0 credits, grading scale: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability. The examiner may apply another examination format when re-examining individual students. If the course is discontinued, students may request to be examined during the following two academic years.
Examiner
Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
