摘要
针对心电信号中含有噪声的现象,为了准确提取反映心电信号的特征信息,该文提出了应用一维离散小波变换实现对心电信号的降噪处理方法.研究结果表明,该方法能够有效地去除心电信号中的噪声,从而为进一步实现心电信号特征信息的提取提供了有效的参考价值.
According to ECG signal ’ s noise phenomenon , a noise reduction method that based on one-dimensional discrete wavelet transform was discussed in this paper for accurately extract the characteristics of the ECG signals .The results demonstrate that this method can effectively reduce the noise of the ECG signals , which provide a useful reference value for further extracting features information of ECG signals .
