RE: [TCML] RFI EMI Filter question

["Lau, Gary" <Gary.Lau@xxxxxx>]

Using two filters in series may help, although no one really has any idea how effective they are - we don't know how to measure that.  The best thing one can do to minimize such problems is to use a good RF ground.  What are you using?
