| 摘 要： | 心电信号是一种极易受环境影响的微弱信号,其中夹杂的各种干扰噪声增加了心电信号的分析和诊断难度.针对心电信号中的肌电干扰信号,设计改进型分布式FIR低通滤波器.以MIT-BIH心电信号数据库为样本信号,对该滤波器进行数值仿真和电路测试,研究表明该滤波器能有效滤除肌电干扰信号,能提升信噪比、降低均方差,提高心电信号检测的准确率.因此,该设计对去除肌电干扰信号是有效和可靠的.

| Abstract: | ECG signal is an extremely weak signal.It often mixes with all kinds of noise and is easily influenced by the environment, which increases the difficulty of analysis and diagnostic ECG signal.The FIR filter of improving distribution was designed, which regarded the sample of MIT-BIH ECG database as the original signal.After testing and numerical simulation to the filter,the result showed that the filter could successfully filter out EMG interference signal, improve the SNR, reduce the MSE and improve the accuracy of ECG signal detection.Therefore, the design of removing EMG interference signal was effective and reliable. |
