hello everybody,
I am using the USRP with LFRX daughterboard to catch an RFID signal ASK modulated (frequency 13.56MHz, decimation factor 16). I really need an help because I don't understand very well the meaning of the outputs of my USRP: if the information related to the ASK is only the amplitude, so why USRP outputs I/Q samples? Which is the meaning of the Q samples? Which is the information carried by the phase (that should not be important in ASK modulation)? If I want to plot in the time domain the samples got, which kind of operation is necessary (given that I would compare my result with the usrp_oscope.py)? Any kind of help will be really well appreciated. Thank you, Marco _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
