Figure 14From: The extraction of the new components from electrogastrogram (EGG), using both adaptive filtering and electrocardiographic (ECG) derived respiration signalThe examples of EGG signals spectra with added components (0.12, 0.15, and 0.22 Hz). Spectra for EGG signals after classical filtering in range (0.015–0.5 Hz) (left); spectra of the same EGG signal after adaptive filtering (right).Back to article page
