Abstract: A signal waveform analyzation technique which filters digital data to define primary peaks. Unfiltered data of the primary peaks is then employed to define secondary peaks associated with the primary peak. Amplitude and time characteristic data associated with the secondary peaks is then employed to determine reproducibility of secondary peaks between the pair of traces. A hierarchial analysis is utilized to further analyze the reproducible pairs of secondary peaks to identify a prominent wave. Depending on the success of a first pass, the digital data is filtered with a different bandpass, whereupon the analyzation steps are again repeated in an attempt to identify a prominent wave.
