[Discuss-gnuradio] USRP and RFX2400 block diagrams

[Lee Patton]

I've taken a shot at coming up with block diagrams for the USRP and
RFX2400.  The diagram for the USRP is the result of information I've
gleaned from different messages in the list, data sheets, and block
diagrams created by other GNU Radio users (specifically, Achilleas
Anastasopoulos).  The RFX2400 diagram was created from Matt's drawings
and associated data sheets. 

The diagrams can be found here:

Hopefully this will help clear up questions regarding how the I/Q
sampling happens. Please let me know if (when) you see something that
needs fixed.

Thanks,
 Lee
