Why doesn't any but Trev get this? Trev.......tell this guy. Steve - Go try DSSF3 - FFT is only part of the issue. This suite of programs is free for a month and has more tools than I've ever seen anywhere in one package. Take you 1/2 hour to pin it ALL down.
We are not dealing with a straight forward ANYTHING here. We are dealing with sub-subharmonic hybrid LF sine waves caused by commutation of thyristors. The band-pass filters are used for single and 3-phase phase balancing so that the B-PLC SCADA system can inject its modulated carrier wave. You don't NEED any measurement filters to get this noise, just a straight mic. The noise is audible and as real as anything else out there. This has nothing to do with peaks, especially not 60Hz. Has everything to do with interphasic reactance, sub/interharmonic and power sine wave reactance, amplification of hybrid emmisions, and attenuation. i.e There is a reason WHY "they" are trying to get rid of phase shift and attenuation. It does cost a lot of $$ to accomplish. Everybody wants to do their own thing - That's why nobody has ever nailed this down. Simple instructions as in the above posts just simply get ignored. DUH..... What WE ALL hear is between 15 and 30Hz REAL noise folks! No mystery, magic, ghosts, or otherwise. Now let's all go and file some legal complaints here now that we have the tools to produce the evidence to back up our claims.
