AN APPLICATION OF AUTOCORRELATION METHODS TO THE INTERPRETATION OF INTESTINAL MOTILITY RECORDS
Melvin D. Small, John W. Brean, John T. Farrar · The Journal of General Physiology · 1955
The application of statistical communication techniques to the analysis of intestinal motility records has made available certain information that has heretofore been obscure. This information is: 1. A measure of total activity expressed in square millimeters of Hg. 2. The frequency and amplitude of segmental activity. 3. A measure of the random variations in the amplitude of the "segmental" waves. 4. A measure of random activity and the range and relative amplitudes of the frequencies making up this component.
