摘要
针对心电信号自动分析和处理的需要,采用小波变换的方法对心电信号进行消噪、特征提取、压缩等分析与处理,并且结合虚拟仪器LabVIEW设计实现了多功能虚拟心电信号分析仪。实验结果表明,它对于心电信号的自动检测、优化分析和处理有重要意义。
According to the need of auto analysing and processing of the ECG signal, the paper introduced the method of wavelet transform to analyze and process the ECG signal such as denoising, feature extraction, compression and so on. A multi- functional virtual instrument with LabVIEW was designed to achieve analysing and processing of the ECG signal. The experimental results show that it is significant for auto detecting, optimal analysing and processing of the ECG signal in practice.
