Abstract
A filter board for filtering electromagnetic emissions from an electronic device couples to a conductive housing in the device. The filter board includes a plurality of filter components connected to a substrate, which is coupled to a continuous ground plane. Signal lines from the electronic device are coupled to the filter components and pass through the substrate and ground plane before being connected to other circuits. The filter board prevents high frequency noise and excessive emissions from exceeding required limits.
