| Abstract: | Expounded in this paper is the removal of apparent and seeming errors frequently seen in ECG signals through breakdown and reconstruction of dyadic wavelets. Experiments show that it is possible to quickly and effectively remove such errors caused by muscle trembling, float displacement of base lines and AC frequency interference so as to ensure correct judgment of ECG signals. |
