⛄ 内容介绍

为了进一步优化滤波器设计.便于及时调整滤波器的参数,提出了基于MATLAB平台利用滤波器设计与分析工具箱设计数字滤波器.阐述了数字滤波器的基本原理和滤波器设计的操作步骤,并进行仿真模拟.结果表明:所设计的滤波器可以有效抑制干扰信号,提高信噪比;设计过程快速简单,方便根据实际需求调整滤波器的参数,适用于工程实践中.

⛄ 部分代码

function varargout = untitled(varargin)

% UNTITLED MATLAB code for untitled.fig

%      UNTITLED, by itself, creates a new UNTITLED or raises the existing

%      singleton*.

%

%      H = UNTITLED returns the handle to a new UNTITLED or the handle to

%      the existing singleton*.

%

%      UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in UNTITLED.M with the given input arguments.

%

%      UNTITLED('Property','Value',...) creates a new UNTITLED or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before untitled_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to untitled_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".
