Question(s) Regarding DSP|Options Tab & undocumented function (PowerSDR/Flex 3K)

JDE

I was going through the PowerSDR Setup | DSP | Options Tab and was wondering what the "Leak" parameter does for NR and ANF. I could not find any reference to it in the existing Flex 3000 documentation.

Other related questions:
 - What are the units of measure for related functions: Taps, Delay, Gain & Leak?

Thanks!

    Anyone? Tim? It's not a dumb question if you really don't know. Someone point me in a helpful direction to find this info out? "Inquiring Minds Want To Know"!

    If you like reading, and excel at mathematics image, Then maybe you will find this documentation useful. It made my head hurt! image Scanning my way thru it, i found explanations about Taps and Leakage, in regard to FFT and Digital Filtering. But I found no hints about how to adjust the NR and ANF filters in PowerSDR. The defaults ought to at least be written down, before you do any customizing. I wish I had a useful definitive answer for you, but maybe, the answer is in this document, it might at least help explain the lack of responses your getting. ...
