1. A method of determining the location in time of maxima and/or minima of an oscillatory signal, the method including the steps of:

  • i) observing the amplitude of the oscillatory signal over a predefined measurement period and identifying local maxima or minima that have a preselected measure indicative of the size of the maxima or minima, which exceeds a certain threshold;

    ii) computing an average interval between local maxima or minima identified in step i);

    iii) computing the duration of one or more exclusion periods dependent on said average interval;

    iv) determining a location in time of the one or more exclusion periods based on the observed signal;

    v) detecting local maxima or minima in the observed signal and rejecting a maximum or minimum if a maximum or minimum is located in time within an exclusion period.
