【数字信号】基于Matlab GUI数字均衡器设计【含Matlab源码 904期】

一、简介

基于Matlab GUI数字均衡器设计

二、源代码

function varargout = balancer(varargin)
% BALANCER MATLAB code for balancer.fig
%      BALANCER, by itself, creates a new BALANCER or raises the existing
%      singleton*.
%
%      H = BALANCER returns the handle to a new BALANCER or the handle to
%      the existing singleton*.
%
%      BALANCER('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in BALANCER.M with the given input arguments.
%
%      BALANCER('Property','Value',...) creates a new BALANCER or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before balancer_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to balancer_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
