Noise rejection filter in electrocardiograph and filtering method Therefor

摘要

The present invention relates to a noise classification filter device and a filtering method, and more particularly, to a noise classification filter device and a filtering method for removing or reducing noise from an electrocardiograph (ECG) signal. A noise classification filtering apparatus for removing noise of an electrocardiogram signal according to an embodiment of the present invention includes signal analysis means for performing signal analysis in a frequency domain on a raw ECG signal captured through an electrode; And pattern classification means for continuously comparing the signal analysis result with the previous signal analysis result to discriminate between a constant signal pattern and an irregular signal pattern, and to increase the discrimination ability for the signal through learning of the singer signal. Means for indicating the accuracy of the signal with probability; It characterized in that it comprises a; signal monitoring means using two periods of different time.
