Abstract

A method of determining the periodicities of gastrointestinal data using an autoregressive modelling technique is presented. The method has been applied both to simulated sinusoidal data and to gastrointestinal and colonic data. Unlike the fast Fourier transforms, the method presented is both automatic and capable of yielding frequency estimates on as little as 5 cycles of data corrupted with noise.
