The need for EMI Filters

To meet regulatory requirements, such as those put in place by the FCC and the EU Directive on EMC, EMI (electromagnetic interference) filtering is now an essential element of equipment design.

Introducing screening measures, e.g. to the case or cables, may suffice in many instances, but some form of low-pass filtering will often be required.
