The reason for the noises are of course EMC problems, aka electromagnetic compatibility problems. That is why I will explain the reasons for EMC problems, how to measure them and how to fix them as well. While doing so, I will not only talk about mains filter but also about other areas of the EMC. Let's get started! Thanks to the Würth Elektronik eiSos Gruppe for supporting this video.
