EMC – the invisible ghost
The development of electronics used to be relatively simple because the existing components were less integrated and complex. In earlier days, people could repair a radio themselves, but today you will not be able to do so without having completed a Master’s degree in Electrical Engineering. The rising complexity can also be seen in the testing of electromagnetic compatibility (EMC). For instance, small changes in the cable routing can be crucial for the question if a device can pass the respective test.
