Abstract

A clock signal having a predetermined phase relation­ ship relative to a signal element of an analog signal that repeats at a nominally fixed frequency is generated by an oscillator having an oscillation frequency that depends on the value of a control signal. The input analog signal is sampled under control of the clock signal, and a succession of digital words representing the amplitudes of the succes­ sive samples is generated. The digital words are written into memory, and are digitally analyzed in order to determine the phase, within the cycle of the clock signal, of the signal element. The signal that represents the phase of the signal element relative to the clock signal is used as a control signal for controlling the frequency of oscillation of the oscillator.
