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?
