No, I'm talking about instantaneous baseband waveform amplitudes generated by an external program and written to a file with a single amplitude value per sample. Also, what is the peak-peak signal values for floating point data sources? -1.0 to +1.0? _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
