Hi Jim,
Great, congrats. I wonder if you could explain a bit
more about the output of your filter bank? What is
the advantage over an FFT? I know of course that
the response is faster, but I wonder if you could go
into a little more detail.
Is the "bin width" (or whatever corresponds to
bin width) constant for all the frequencies? Can
the width be adjusted at run time?
Does the "epoch length" (or whatever corresponds
to that) vary from one band to another?
How do you test the output of a filter bank? Is there
a way to set performance criteria and then
measure to see if the filter matches?
If these are stupid or irrelevant questions can you
substitute better ones? :)
Best regards,
Rob
