Title: Method for generating a signal pulse sequence with a predetermined stable fundamental frequency

Abstract: A method for generating a signal pulse sequence with a predetermined stable fundamental frequency from a sequence of signal pulses whose frequency fluctuates and has the spectral components whose frequency is at least a predetermined multiple of the fundamental frequency. The method includes, feeding the sequence of signal pulses to a digital filter, arranging a passband of the digital filter around the fundamental frequency, blocking, using the digital filter, around a predetermined half the sampling frequency. The method further includes outputting a signed output signal when the digital filter is excited, and generating a clock signal pulse for each change in sign of the output signal.
