Hi,
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 USRP.
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,
Sivaram
