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 即利用数字电路和模拟电路等相关知识,设计了具有输入阻抗大、共模抑制好、增益高等特点的肌电信号前置处理电路,利用“振通”数据采集仪对处理后的信号进行采集,并利用快速傅立叶变换的相关知识编写了信号处理程序,对肌电信号进行了波形分析、幅值谱分析和功率谱分析,提取了信号特征值,与相关资料的数据相比,基本一致;二是利用肌电信号的特征值对肌电假手进行控制。
