The USRP hardware will only decimate by up to 128 at this time. That will give you 500 ks/s complex and 500 khz of BW. In software you should then pass the signal through a decimating FIR filter to get it down to the width you'd like. Nearly all of them examples show how to use one of these filters. > How could I add a bandpass filter to usrp_rx_file.py? Is this even the > right way to go?
