I was wondering, is there anything in particular that’s peculiar about
a filter to isolate one sine wave out of three that are being
over FM? I’ve attempted adding another FIR (optfir) filter post-demod,
connecting it to the pipeline produces a long list of small floats in
terminal (filter coefficients, perhaps?), and then the program
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
What’s the proper method for filtering signals, then? It looked fairly
straightforward, but perhaps optfir doesn’t function as I was expecting
to. My code is attached.
