By utilizing the knowledge of digital circuit and simulation circuit , the system designs the pretreatment dealing circuit of the myoelectrical signal , which has the feature of big input impedance well suppress of public module and high gains . then the signal is gathered with " zhentong " data gathering after dealing with , and the software of signal processing is explored before the myoelectric signal is analyzed . after picking up eigenvalue , it is proved that the result is unanimous basically with the data of the relevant materials ; the other is to control artificial hand by the eigenvalue of the myoelectric signa l and at last the system gets very good control results 即利用數(shù)字電路和模擬電路等相關(guān)知識(shí),設(shè)計(jì)了具有輸入阻抗大、共模抑制好、增益高等特點(diǎn)的肌電信號(hào)前置處理電路,利用“振通”數(shù)據(jù)采集儀對(duì)處理后的信號(hào)進(jìn)行采集,并利用快速傅立葉變換的相關(guān)知識(shí)編寫了信號(hào)處理程序,對(duì)肌電信號(hào)進(jìn)行了波形分析、幅值譜分析和功率譜分析,提取了信號(hào)特征值,與相關(guān)資料的數(shù)據(jù)相比,基本一致;二是利用肌電信號(hào)的特征值對(duì)肌電假手進(jìn)行控制。
