I am trying to implement a FM/AM multiplex signal using USRP board, with
Simple TX RX daughter boards.
I need a basic signal to be modulated over FM and use that FM modulated
signal as a base band for AM modulation, which will be finally sent to
I was trying to use blks2.nbfm_tx / blks2.wfm_tx. But in both the
functions, I can specify only the peak deviation but not the center
frequency. Please let me know how do I do an FM modulation by specifying
both Fc and delta-f.
I have one more question. How do I do an AM modulation? I don’t find any
specific function for that. If I just connect the baseband signal to the
tuner card, tuning the usrp subdevice to the carrier frequency, will
that transmit an AM modulated signal?
I appreciate any help at these points at the earliest.
Thanks and Regards,
