Hi
Assume I have a digital PLL that outputs phase estimate of the reference signal, however I am wondering can I estimate the frequency of reference signal according to the given phase estimate? I know frequency is derivative of phase respect to time but dont we need a operating or center frequency of VCO(NCO). Can anyone guide me to find an algorithm to estimate the reference frequency ?:
