基于Matlab的FIR带通滤波器设计及DSP实现

Design of FIR band-pass filter based on Matlab and its implementation with DSP

借助Matlab的FDATOOL滤波器设计分析软件,设计了一种FIR数字带通滤波器,并对一段含噪语音信号进行滤波。利用汇编语言编程,在DSP上实现了该滤波器。实验结果表明,该数字带通滤波器精确,稳定性好,易于移植,具有很强的实用性与灵活性。

Designed a FIR digital band-pass filter with the Matlab′s FDATOOL,and gave a filtering of a noised speech signal.Then this paper implemented the filter on DSP by using of assembly language programming.Results of experiment show that the digital band-pass filter has the characteristic of precision,good stability,ease of migration,strong practicality and flexibility.
