Description: IIR digital filter design commonly used indirect method (impulse response method and the bilinear transform), the most widely used is the bilinear transformation method. Basic design process are: ① the first digital filter given transition indicators into analog filter indicator ② transition analog filter design ③ analog filter system function will transition into a digital filter system function. MATLAB Signal Processing Toolbox in a variety of IIR digital filter design functions are based on the bilinear transform.
