SDR Hardware Functions


In using, I pull complex I and Q data off of the USRP.
was wondering if this data is handled in any analog fashion in the mixed
signal processor, or if the data is only handled in the FPGA.

To be specific, I want to know if, when using the GNU Radio USRP
(like those called by, if the USRP is behaving as a
software-defined radio, or if any filtering or other such
software-implementable functions are instead being handled by the
on the USRP itself

I may not have my understanding of the way the hardware handles signals
quite correct, but hopefully it’s coherent :slight_smile:
