title: A simple algorithm for averaging multiple cycles of waveforms having varying cycle periods.
abstract: We present a simple method for averaging multiple cycles of a waveform having cycles with varying periods. This averaging process preserves the morphology of the waveform by converting fixed time per point data into fixed fraction of cycle data. The algorithms are implemented using the ASYST system, which provides efficient code for performing the computations and permits straightforward integration of the data acquisition and analysis tasks. An example is given of the results of the program in processing cyclical waveforms obtained in respiratory research.
