Apparatus and method for detection and quantification of oscillatory signals

摘要

A method of determining the location in time of maxima and/or minima of an oscillatory signal, includes 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 the 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.
