Essentially, an EMI filter is an electrical device/circuit that will help mitigate the high-frequency electromagnetic noise present on the power lines as well as on signal lines (Fig. 3). 3.

However, many of the components in EMI analysis are parasitic and will not appear on a schematic diagram. When power switching devices operate on and off, they will generate large discontinuous ...
