fir带通滤波器,可将不需要的频率成分的信号滤去(fir bandpass filter unwanted frequency components can be filtered signal)

正规化的逻辑回归，可实现图像的分类识别,如人脸识别，数字识别(Logistic Regression with regularisation, can be used for image classification)

已知一个LTI系统的差分方程为： y[n]-1.143*y[n-1]+0.4128*y[n-2]=0.0675*x[n]+0.1349*x[n-1]+0.0675*x[n-2] 初始条件y(-1)=1,y(-2)=2，输入x(n)=u(n)，计算系统的零输入响应 (known LTI system of a differential equation : y [n]-1.143* y [n-1] 0.4128* y [n-2] x = 0.0675* 0.1349 [n]* x [n-1] 0.0675* x [n-2] initial conditions y (1) = 1, y (2) = 2, input x (n) = u (n), we calculate the zero input response)
