Hello,

I have a question regarding EMI filters. You know, one of those plastic clamps that you put on your cables. Do they really work? If so, how does clamping a piece of plastic helps remove electromagnetic noise (if that's what EMI stands for)? Sorry if this sounds silly to some of you. But I'm trying to justify the costs of paying lots for those plastic clamps on those Transparent or MIT interconnects. I have just been wondering what those things are for. Any input would be appreciated. Thanks.
