In Reply to: No, because the power cord is a resonator. posted by Al Sekela on February 14, 2007 at 13:21:07:
Al:Resonance at one frequency... very high Q... right?
So... do we need to have RFI at this frequency PRESENT in order for it to be "well conducted" by the cable's resonance? Or is RFI typically "white noise like" in nature, that it's pretty much guaranteed that this resonance will be a problem?
Just wondering. I like your explanations though. Thorough, but "laymanized" enough for the rest of us.
Cheers,
Presto
