这是大学毕业时设计的失真度检测仪论文,由模拟陷波器实现的剔除几波,如果改进的话,可以用数字滤波器实现,不过成本更高(It is designed for university graduation thesis distortion detector by analog notch filter removed to achieve a few waves, if improved, you can use digital filters to achieve, but higher costs)

fs=100 采样频率,必须大于两倍基带信号最高频率
ts=1/fs 采样时间间隔
T=2 时间窗大小

x=x+0.1*randn(1,N)
x=awgn(x,-10, measured )
