Re: [Discuss-gnuradio] gnuradio on ubuntu touch

Try decimating after the filter, before you start computing log10 at the input rate.  There's no need to do those calculations at the original

  sample rate once you've computing complex-to-mag**2 and filtered.

Tried that, but still ocurring overflow.    Another thing I had was that on my computer I was using a     complex to mag^2 -> single pole IIR filter -> log10 -> multiply const (10)  to measure the signal strength    that is also causing overflow on the single board computer. If I put a RMS  block instead, no overflow occurs.          --  View this message in context: http://gnuradio.4.n7.nabble.com/gnuradio-on-ubuntu-touch-tp49315p49807.html  Sent from the GnuRadio mailing list archive at Nabble.com.    _______________________________________________  Discuss-gnuradio mailing list  Discuss-gnuradio@gnu.org  https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
