Sažetak
This article describes a new method for the selection of an appropriate signal line Electromagnetic Interference (EMI) filter. It describes an EMI filter selection method based on the signal’s FFT measurement. This selection has proved to be efficient also for quick engineer use. We optimize the EMI filter for each single line separately. The method described in this article involving a Central Processor Unit (CPU) module demonstrates the comparison between new FFT-based selection method and the existent radiation-based one.
