ABSTRACT:
An apparatus for adaptively tuning to a received periodic signal. The apparatus preferably employs digital signal processing techniques for algorithmic generation of a sinusoidal estimated output signal, determines the difference between the estimated output signal and the received signal, and generates an error signal based upon the difference between the estimated output signal and the received signal. The error signal is applied to vary at least one factor of the algorithmic determination of the estimated output signal appropriately to reduce the error between the estimated output signal and the received signal.
