ABSTRACT:
A method and apparatus for filter enhancement in an electrical system (8) is provided. The electrical system (8) includes an input circuit (10) having a filter (14) and an output circuit (20) having a filter (24). An input conductive enclosure (12) and an output conductive enclosure (22) protect the electrical system (8) from field coupling between the input circuit (10) and the output circuit (20). A choke balun (26) is connected between the input circuit (10) and the output circuit (20) to also eliminate conductive coupling. The elimination of unwanted coupling enhances the performance of the electrical system (8) by achieving greater stopband attenuation.
