[Discuss-gnuradio] CIC + halfband filter compensation

[Geoffrey Mainland]

I hope you will forgive a few naive signal processing questions :)

1) What is the frequency response of the CIC and halfband filters in the
USRP? This was addressed long ago on the mailing list
(https://lists.gnu.org/archive/html/discuss-gnuradio/2007-05/msg00191.html),
but the associated MATLAB script is no longer available now that the
nabble archive is gone.

2) How do I design a filter to compensate appropriately?

I know there are other methods for avoiding CIC droop, like
oversampling, but I'd like to understand how to compensate with a filter
as well.

Thanks!
Geoff
