Gang - I'm going back and reviewing the complete signal path from sma socket to speakers, using mux info in usrp_standard.h, Achilleas' *.ps diagrams, etc.
One thing I don't understand tho: if a typical mux of 0xF0F0F0F0 feeds zeros to all DDC Q inputs, and ADC 0 to all DDC I inputs, nchannels = 1 sends data from DDC 0 only, and looking at the DDC block diagram in figure 3 at: http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html how is it we can a complex stream to the software? Why aren't all the Q values also 0 ( zero * nco-cos ) ? Is the decimating low pass filter also a hilbert? --Chuck _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
