摘 要: | 给出了心电信号处理的两种方法。第一种方法是运用合成技术 ,它可以保证波形的完整 ,而且便于实现。第二种方法是运用小波分析。小波变换适用于分析非平稳信号 ,适宜于对心电图数据进行预处理和特征提取。本文应用Mallat算法对心电图信号进行了多尺度分解

Electrocardiogram signal processing using synthesis technique and wavelet transform method |
| |
Abstract: | Two methods for electrocardiogram(ECG) signal processing are presented. The first method is a synthesis technique. It preserves the waveform and easy to implement. The second method is an application of wavelet transform. It is tailored for transient signal analysis, particularly appropriate to pre-processing and features extraction for the ECG data. Employing Mallet algorithm, we decompose the ECG signal into multiple scales. |
