Abstract

Adaptive cancellation of motion artifacts in the electrogastrogram (EGG) is presented. Three different sorts of adaptive filters were investigated, and their efficiencies in cancellation of motion artifacts were compared. These were time-domain, transform-domain, and frequency-domain adaptive filters. A series of simulations was conducted to investigate the performance of these adaptive filters in cancellation of respiratory and motion artifacts. The frequency-domain adaptive filter is shown to have superior performance to the time- and transform-domain adaptive filters in the cancellation of stationary respiratory artifacts in the EGG
