[The application of adaptive line enhancement filter in extracting cutaneous electrogastrogram].
Based on the principle of adaptive filtering, The higher signal-to-noise ratio of electrogastrogram data can be extracted from abdomen skin with the adaptive line enhancement filter. The design method of feedback factor and filtering coefficient is introduced in this paper. Experimental and practical results show the method is effective.
