心电滤波求助
我用了matlab的fdatool做了一个fir滤波器，低通40hz，用kaiser窗 beta = 0.5,order = 16,fc = 40，滤波后发现波峰幅值衰减。系数：b = [-0.02663578587251,-0.0147574298586,0.00593588424016,0.03376056548383,0.06552466686714,0.09701005074269, 0.1236915864871, 0.1415531852662,0.1478345532879, 0.1415531852662, 0.1236915864871,0.09701005074269,0.06552466686714,0.03376056548383,0.00593588424016,-0.0147574298586,-0.02663578587251]。有什么方法能够去除干扰又不影响波形？对心电信号滤波用什么方法好？
