The inductors of the DM separation unit are coupled such that a substantially ideal zero impedance is presented to DM noise while a high impedance is presented to CM noise. Conversely, the inductors of the CM separation unit are coupled such that a substantially ideal zero impedance is presented to CM noise while a high impedance is presented to DM noise.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/79/985/086/0.pdf13071647333/181333/12G01R31/001H03H7/427H03H7/09H03H7/1725H03H2001/0058698579
