Thanks for your help,

Thank you Brian & Matt
Using Matt HBF coefficients given by the verilog file [coeff_rom.v], I did
the HBF frequency response analysis by MATLAB FDATOOL. Attached is the USRP
HBF result frequency response. As we can see, there is a 6 dB passband gain.
In my next step, I will try to provide the f

Firas,
The coefficients are here:

Dear Hans,
I think you meant the frequency response of CIC+ HBF filters. However, the
USRP CIC decimation filter has 4 sta
Hans:
I don't think you really want the CIC transfer function but the transfer
function of the convolution of the half band filters and the CIC since
that is the total transfer function through the FPGA. Am I right?

It's a fourth order CIC.

Hello,
What is the stop band of the FPGA CIC filter? How do I figure out the
attenuation at a given frequency outside my bandwidth?
I'm decimating by 250.
Thanks,
Hans
