Abstract

The present invention provides a system and method for representing quasi-periodic ('qp') waveforms (1400) comprising, representin a plurality of limited decompositions of the qp waveform, wherein each decomposition includes a first and second amplitude value and at least one time value. In some embodiments, each of the decompositions is phase adjusted such that the arithmetic sum of the plurality of limited decompositions reconstructs the qp waveform. These decompositions are stored into a data structure having a plurality of attributes, Optionally, these attributes are used to reconstruct the qp waveform, or patterns or features of the qp wave can b determined by using various pattern-recognition techniques.
