    Abstract: The study reported in this paper analyses, by computer simulation, factors affecting the features (amplitude, frequency and phase lag) of the slow waves of the extracellular myoelectrical activity of the human ascending colon. It takes into account both the anatomic and functional aspects of the colon haustra, the myoelectrical dynamics of the cell... Show More

    Abstract: The coherence function provides a measure of spectral similarity of two signals, but measurement noise decreases the values of measured coherence. When the two signals are the input and output of a linear system, any system noise also decreases the measured coherence values. In digital computations, useful coherence values require some degree of av... Show More
