Filter Function

Filters in EMI Analyst are circuits comprised of passive electrical components.  Generally, the purpose of a filter is to attenuate unwanted signals.  However, a filter can also amplify signals in select frequency ranges.

In the CE Analyst and RE Analyst applications of EMI Analyst the filter is positioned between the Source and the Conductors.  In most cases the job of the filter is to attenuate the signals produced by the Source so that the signal levels that reach the Conductors are below the conducted emissions limit and/or don't produce radiated emissions that exceed the radiated emissions limit.
