摘要
在运动康复治疗中,需要一种即能够滤除信号中的干扰,又能够放大信号的有源滤波器提取相关肌肉运动产生的表面肌电信号,以评估康复治疗效果。基于多重反馈型滤波器设计一种表面肌电信号的有源低通滤波器,并通过仿真进行验证。
In the exercise rehabilitation treatment,an active filter that can filter out the interference in the signal and amplify the signal is needed to extract the surface EMG signal generated by the related muscle movement,so as to evaluate the effect of rehabilitation treatment.Based on multiple feedback filter,an active low-pass filter with sEMG signal is designed and verified by simulation.
