摘要：

In this paper, at first, three requirements for noise separators are specified and the disadvantages of traditional evaluation methods are pointed out. Noise separators are then characterized using scattering parameters (S-parameters). Existing noise separators are evaluated according to the specified requirements. Finally a noise separator is proposed with parasitic controlled design and the prototype is evaluated using the proposed method. An electromagnetic interference (EMI) measurement shows that the proposed noise separator can effectively separate noise and that it is easy to use.
