  • Patent number: 5795304
    Abstract: A method and system for analyzing an electrogastrophic (EGG) signal are disclosed. Electrodes are positioned on abdominal skin of a subject adjacent a stomach thereof. The electrodes obtain the EGG signal produced by the stomach. An amplifier is connected to the electrodes, receives the obtained EGG signals, and amplifies the obtained EGG signal. A transforming device is operatively connected to the amplifier. The transforming device receives the amplified EGG signal and transforms the amplified EGG signal from a time domain representation to a frequency domain representation. The transformation is accomplished by way of a predetermined transform function incorporating a variable frequency and a window function. The window function has a time resolution and a frequency resolution. The frequency resolution of the window function is proportional to the frequency.
