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

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!

    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. ...

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
