SDR IF Domodulation

Expert 1190 points


SDR being softwear defined radio. I want to input thru stereo in the IF, demodulate it in dsp and output to headphone out.

Any suggestions where I start. I am using the ezdsp USB 5505 stick.

I want to read, freq shift and output.

    Hello Martin,                                  Sure - You should be able to do this.  Not sure about your source - but you can look here for some initial ideas - www.winrad.org - you can use one of the Softrock receivers for your IF I/Q and your `5505 board to  process the audio.  Not sure really why your post went unanswered.  Have a look too at what Ettus Research is doing.                                                HTH, johnw
