Abstract: A method for removing noise from a signal and an electronic device are provided. According to the method, by virtue of a continuous abrupt change performance of a wave peak having reference significance in an electrocardiography signal, whether a signal point is a point on a signal wave having reference significance can be identified during noise removal, and whether to remove noise from the signal point can be determined. The method is implemented, so that noise can be effectively removed from the electrocardiography signal on the premise that a reference value of the electrocardiography signal is guaranteed.

Abstract: This application provides an electrocardiogram signal quality evaluation method, an electronic device, and a chip system, and relates to the field of signal evaluation technologies. In this method, peak variability features and peak number variability features of a plurality of electrocardiogram signal samples are counted, based on the peak variability features of the plurality of electrocardiogram signal samples as one abnormal dividing point, and the peak number variability features of the plurality of electrocardiogram signal samples as another abnormal dividing point; and based on a relationship between a peak variability feature and a peak number variability feature of a to-be-evaluated electrocardiogram signal and the two abnormal dividing points, whether the to-be-evaluated electrocardiogram signal is a normal signal, an abnormal signal, or a noise signal is determined.
