Description: The important aspect of the digital filter is a digital signal processing, digital IIR and FIR filter may be divided into two categories. This article describes the basic design principle of IIR and FIR, as well as how to use the MATLAB environment direct programming method the SPTOOL Design Law and FDATOOL of design method given IIR and FIR digital filter design methods and steps and design design example is given and operating results, while taking advantage of simulation software SIMULINK MATLAB environment of filter design simulation, design parameters set reasonable simulation results indicates.
