摘　　要： 人类的肌肉电信号是一种相当复杂的微弱信号,根据肌肉电信号的特点,采用虚拟仪器设计开发了一套肌肉电信号的采集和处理系统,该系统采用自适应滤波器,基于LABVIEW和MATLAB编程完成。通过这一系统可以对肌肉电信号进行时域分析、频域分析和采集数据的管理。实验证明,该系统具有自动化程度高,测试灵活,信号采集准确可靠,数据处理能力强等特点。 EMG is a very complex and delicacy signal.Based on the character of EMG,a practical signal collecting and processing system was developed by using virtual instrument software.An adaptive filter was designed to filter noise from the signal sampled.The filter was development by the LABVIEW and MATLAB.The analysis of time domain,frequency domain and the management of sampling data can be completed in this System.The results show that this system has the features of high level of automatic flexiblity of test,accurate sampling and strong ability of data processing.
