HI all:
I wrote to Rob, asking when he would post his findings on the various
BW filters and as a result, it's there now!
http://www.sherweng.com/table.htmlSee the first line (top entry) on his URL and look over to the
right-hand side. Results for three filters are listed vertically.
The "key" is at the bottom of his page.
In a nutshell:
Filter DR "narrow spaced" (2kc)
200hz 5 pole 101
400hz 8 pole 96
500hz 5 pole 95
In Rob's own words, you'd be hard pressed to tell the difference in DR
between the 400 and 500.
He also had some other comments, which he said that I could post on
the reflector, but which I am not yet motivated to do. If you want a
copy of his full reply, please let me know. If I get enough requests,
I'll post it to the reflector.
