Is there a code snippet I can look at which would describe this?How do I select the appropriate sampling rate, if_decim, if_rate, etc.? E.g. if I choose a sampling_rate of 16 kHz to generate the sine waves, what do I need to set my usrp_tx_interp rate to in order to achieve a corresponding output? Do I need to further interpolate or decimate this signal before passing it to the USRP? Also, should I be using complex_to_float() or something else?
Now, suppose I want to broadcast to N AM radio stations whose center frequencies are X + [x1, x2, x3 ... xn]. What changes? Do I use the freq_xlating_filter with the offset equal to [x1...xn]? If so, what parameters do I provide?
I've looked through the NBFM files, but they're more complicated than what I want at this point.
Thanks, --Alex
