The allowable audio rates are determined by your sound card. Commonly supported rates are 8000, 16000, 32000, 44100, and 48000. Some higher end cards support 96000 and/or 192000. Most cards support samples between 16 and 24 bits. > > 2. What are the factors on which the sampling rate depends in USRP? The interface to the USRP is specified in the comments in these two files: usrp/host/lib/usrp_basic.h and usrp/host/lib/usrp_standard.h. There is a python wrapper defined in gr-usrp/src/usrp1.i that exports the equivalent of these interfaces to python. This includes how to set the DDC and DUC frequencies, sample rates across the USB (based on the interpolation and decimation factors), etc. The A/D's always run at 64MS/sec. The D/A's run at 128 MS/sec. Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
