Ok, thanks, One more question… So does that mean we control the NCO
from the software?
I will have a look at those blocks.

Thanks for the reply. I guess I am just trying to better understand this
I understand what the decimating filters are doing, but I’m a little
unclear about the NCO. Does this component phase and frequency lock for
me, or will I have to code that myself?
No, there is no freq/phase lock in the USRP/USRP2. We have to do this in
You can reference the dbpsk and dqpsk blocks that we have already
written or the newer dbpsk2/dqpsk2 blocks that use newer techniques for
the phase, frequency, and timing locks.
