Abstract:
Body-surface electrogastrogram signals can be adopted in studies of gastrodynamics characteristics and diagnoses of functional gastric diseases. Fundamental theory of denoise by wavelet introduced, wavelet transfer is applied to the denoise of body-surface electrogastrogram signals. The high-frequency noise is eliminated through wavelet, and thus the SNR and the resolution ratio of the signal are increased.
