The use of electrogastrography performed with cutaneous pre-gelled electrodes located in the region above the stomach to record electric control activity is discussed. A real-time spectrum analysis is used to provide a graphic representation of this activity. This study provides a method for the automatic determination of the gastric activity independently of the relative position of the stomach and the electrodes. The proposed method amplifies regular noise such as respiration. An adaptive filter is needed to suppress this noise and improve the quality of the recording. >
