Where do unwanted harmonics come from?
Did you know that just your regular diode can cause unwanted harmonics? In this video, Gregor Böhm and Rui Mi explain what harmonic distortion is, how to look out for it, and how to measure it. Learning outcomes: After watching the video, learners can: explain why a non-linear device causes harmonic distortion. list sources of harmonic distortion. describe how a source can be measured. Chapters: 0:00 - Introduction 1:00 - Theory: Diode 2:02 - Theory: Contact harmonics 2:35 - Experiment: Introduction 6:16 - Experiment: TVS diode 7:25 - Experiment: Contact harmonics 10:57 - Conclusion This learning video is part of the upcoming course "EMC measurement instrumentation" which the Institute of Electronics is producing with the Austrian Chips Competence Center.
