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.

Graphical and Analytic Representation of Sinusoids
The first step is measuring the peak-to-peak value, which is twice the amplitude of the sinusoid. This provides information about the maximum voltage swing of the waveform.
Secondly, the period and angular frequency are determined. The period is the time taken for one complete cycle of the waveform, while...
