Abstract

Electrogastrography(EGG) has been an attractive method for physiological and pathophysiological studies of the stomach and now is on the verge of becoming a new clinical tool in gastroenterology. In this study 4 channel EGG measurement system was constructed and running spectrum analysis was developed for 2D and 3D display of power spectrum with time and frequency. A wavelet multiresolution method was utilized for elimination of baseline drift and for filtering out noises.
