Hey all, I was wondering, is there anything in particular that's peculiar about using a filter to isolate one sine wave out of three that are being transmitted over FM? I've attempted adding another FIR (optfir) filter post-demod, but connecting it to the pipeline produces a long list of small floats in the terminal (filter coefficients, perhaps?), and then the program terminates. Otherwise, the program is identical to usrp_wfm_rcv_nogui.py. It runs as normal when the filter is commented out, outputting all signals at a specific FM frequency to the sound card. However, I don't accomplish my task with that.
What's the proper method for filtering signals, then? It looked fairly straightforward, but perhaps optfir doesn't function as I was expecting it to. My code is attached. http://www.nabble.com/file/p22029608/usrp_wfm_rcv_filt_nogui.py usrp_wfm_rcv_filt_nogui.py -- View this message in context: http://www.nabble.com/Filtering-USRP-FM-Reception-tp22029608p22029608.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
