Colonic Slow-Wave Analysis - Limitations of Usefulness of Fast Fourier-Transform (Fft)

The fast Fourier transform (FFT) has been used to determine frequency components of colonic slow-wave activity. We studied the effect of (1) recorder filter characteristics, (2) number of data points and, (3) data window overlap technique and ingestion of a 1000-kcal meal on the resulting power spec...
