This covers the CIC portion: http://gnuradio.org/redmine/repositories/annotate/gnuradio/gnuradio-core/src/utils/plot_cic_decimator_response.m This useful going the other direction; i.e., compensating for the CIC passband droop: http://gnuradio.org/redmine/repositories/annotate/gnuradio/gnuradio-core/src/utils/cic_comp_taps.m One way to model the HB response would be to use the actual taps as an impulse response and go from there. You can dig them out of the Verilog source code in the Ettus repository (sorry, don't have a link at the moment.)
