Subject: | [Discuss-gnuradio] sending single tone Am modulated using usrp1+wbx |
Date: | Fri, 4 Jan 2013 19:24:32 -0600 |
Hi, I want to transmit and receive a 1kHz cosine tone using dsb am modulation and usrp1 with 2 wbx dbs, I have connected from tx/rx output wbx-a to rx2 input wbx-b with a 50ohm sma cable, I’m expecting in scope sink the cosine tone with 1KHz but I have another signal, can you tell me what could be the error?
I’m based on the complex envelope theory: I=Ac(1+m(t)) Q=0
You can see the diagram and the signals on the attached image.
Thanks.
