Abstract :
The electrogastrography (EGG) is considered more and more important due to its noninvasive measurement. Some parameters have been used to assess the EGG signals and the short term Fourier transform was the most commonly used tool to evaluate these parameters. However FFT is used to analyze stationary signals, while non-stationary signals such as EGG may be distorted. A new method based on discrete wavelet transform was achieved to analyze the power distribution of the EGG signals
