Abstract
A phase locked loop comprising: an oscillator for generating an output signal of a frequency that is dependent on an input to the oscillator; sampling means for generating a sequence of digital values representing the output of the oscillator at moments synchronized with a reference frequency; a difference unit for generating a feedback signal representing the difference between successive values in the sequence; and an integrator for integrating the difference between the feedback signal and a signal of a desired output frequency; the signal input to the oscillator being dependent on the output of the integrator.
