I am new to GNU Radio and I am still learning the basic. I have a quick question. What blocks and which
way can I use in order to "sample" and know the phase of a tuned carrier
at regular intervals.
General idea: Let's suppose there is a carrier, after applying
proper tuning (Freq Xlating FIR Filter, etc), I apply a PLL module (not
sure which: PLL Carrier Tracking or PLL Ref Out) in order to remove
possible drift from the receiver and output a steady carrier. How can I sample at regular
interval that corrected carrier phase. Assuming that intervals are
really equals I guess every time I should obtain the same phase value.
I will really appreciate any help in this matter, perhaps someone could point me in the right
