Abstract: A signal processing system and method are disclosed for generating a composite signal from a plurality of periodic or quasi-periodic source signals originating from independent measurement sources. Portions of the source signals associated with recurring events are transformed into a common representation space using a reversible deterministic transform. In certain embodiments, the transform comprises a length-normalization operation that maps source-signal portions having different durations into a common representation space using interpolation, decimation, spectral-domain resampling, spline resampling, or another invertible resampling operation. Representations corresponding to the plurality of source signals are combined, including by linear superposition of corresponding representation elements, to generate a composite representation. An inverse of the reversible deterministic transform is applied to the composite representation to generate a reconstructed composite signal having temporal correspondence with at least one source signal. Recurring events may be identified using deterministic fiducial-point localization. Fig. 2
