EMI suppression filters and pulse Waveforms - EMI suppression filters' effects on signals and their behavior under transient conditions need to be considered when they are incorporated into equipment

摘要

THE PERFORMANCE OF EMI SUPPRESSION filters is almost invariably expressed in terms of insertion loss; i.e., the reduction in the sinusoidal voltage occurring at a load when the filter is introduced into the system. However, suppression filters commonly encounter two generic types of waveform that are not usually characterized by filter manufacturers. These are digital data waveforms and voltage transient waveforms.
