Hello everyone, I was going through some gnuradio documentation (on comsec.org wiki) which says "...16-bit I and 16-bit Q data (complex), resulting in 8M complex samples/sec across the USB (32 Mbps max. data rate). This provides a maximum effective total spectral bandwidth of about 6MHz...".
By Nyquist criteria, should not this be 4 Mhz? Also, I found this note at some other place which said that we can sense spectrum upto +/- 15MHz from the carrier frequency. Which one of the above is correct? And what is bottleneck for maximum amount of spectrum we can sense at one time, is it limited by the usb bus speed? Also, the in the program "usrp_spectrum_sense.py [options] min_freq max_freq", is there a limit on (max_freq - min_freq)? Thanks, Shravan. PS: My DSP background is zilch. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
