I'm trying to figure out how the x-axis units work on the fftsinks. In
the application "am_rcv.py", the first plot shows the incoming data
plotted as an fft, however the units are centered about 0 kHz. In another
application, say usrp_wfm_rcv_pll.py the units are centered about the
actual frequency of the carrier. Why is this? The fft sink in both cases
is plotting the fft of the source, so I don't see why there should be a
difference.
thanks,
eric
