基于Matlab的IIR数字滤波器设计及DSP实现

Design of IIR digital filter based on Matlab and implementation of DSP

IIR滤波器是一种被广泛应用的基本的数字信号处理部件。基于DSP信号处理的优越性,将Matlab与DSP相结合应用于IIR滤波器的设计。介绍了IIR数字滤波器的理论及其Matlab常用设计函数,并针对TI公司的TMS320VC5416 DSP,结合某高通滤波器的设计,给出了其Matlab仿真设计及在DSP上的实现过程及结果。该方法具有较强的实用性,对其它数字滤波器设计及DSP实现提供了参考价值。

IIR filer is a basic processing unit for digital signal in common use. Based on the advantages of dsp in singnal processing,IIR filter was designed by combining matlab with DSP.The paper introduce the principle of IIR digital filter and Matlab common function,and for the TI TMS320VC5416 DSP,combined with a high-pass filter design,the process and results of Matlab simulation design and DSP implementation are given.The method is practical,and for other digital filter design and DSP implementation provides a reference value.
