基于Matlab／Simulink的滤波器设计仿真技术的实现

Filter design to realize simulation based on Matlab/Simulink

建立滤波器设计系统的Simulink仿真模型，进行仿真分析，实现滤波器设计仿真技术。本文主要介绍使用Matlab的SignalProcessingToolbox工具箱中可视化滤波器集成设计环境一滤波器设计及分析工具（FilterDesignandAnalysis Tool）．借助于FDATool强大的交互式图形用户界面，可以直接设置滤波器的性能指标、直接赋值滤波器系数来进存滤波器设计．然后用Simulink对系统进行可视化建模及仿真。

To establish the simulink modal of filter design system and make simulation analysis to realize emulation of filter designer ,this text proclaimed how to use Signal Processing Toolbox in Matlab which include visualization Integerate design environment-Filter Design ＆ Analysis Tool. By using the powerful interactive ability of graphic interface in FDATool , User can directly set Filter parameter and Filter function index to establish Filter design, Finally user can create visual model to emulate filter design by using simulink.
