[Discuss-gnuradio] CIC passband compensation

[Nirali Patel]

Hi,

I am trying to understand the USRP receive chain response and referred to 
earlier posts that gave me almost all the information that I needed. However, I 
am unsure whether the HB filter compensates for the passband droop that occurs 
in the CIC. My understanding of the CIC was that the frequency response has a 
sinc like function and is typically followed by a FIR which compensates for the 
sinx/x shape in the passband. Does the HB filter response compensate for the 
non-flat passband of the CIC? 

Thanks,
Nirali
