基于MATLAB高阶带通滤波器的设计与仿真
摘要:传统的数字带通滤波器的设计过程复杂,计算工作量大,滤波特性调整困难,影响了它的应用,尤其是设计高阶带通滤波器。本文介绍了几种基于MATLAB高阶带通滤波器设计方法,并利用MATLAB信号处理工具箱(Signal Processing Toolbox)快速有效的设计由软件组成的常规数字滤波器的设计方法。给出了使用MATLAB语言进行程序设计和利用信号处理工具箱的FDATool工具进行界面设计的详细步骤。利用MATLAB设计滤波器,可以随时对比设计要求和滤波器特性调整参数,直观简便,极大的减轻了工作量,有利于滤波器设计的最优化。最后利用MATLAB环境下的仿真软件Simulink对所设计的滤波器进行模拟仿真。

Use MATLAB to Design and Simulate the higher-order bandpass filter
 
Abstract: The traditional digit bandpass filter's design process is complex, the computation work load is big, the filter characteristic adjustment difficulty, has affected its application, particularly designs the higher order bandpass filter.This paper introduces several based on MATLAB higher-order bandpass filter MATLAB design methods, and Signal Processing Signal Processing Toolbox (Toolbox) fast and effective design by the software design method of conventional digital filter. Given the use of MATLAB language program design and use of signal processing FDATool toolbox of tools for interface design detailed steps. MATLAB design filter, can design requirements and filter characteristic comparison, easy adjustment parameters, reduce the workload, be helpful for the optimization design of filter. This paper also introduces how to use MATLAB simulation software Simulink for design of filters simulation.
Keywords: digital bandpass filter MATLAB FIR IIR
