一个用MFC写的滤波器源代码，代码结构非常精巧，可以参考

功能：1 固定带通滤波

2 可变带通滤波

3 噪声删除

4 输入输出误差计算



实现比较简单，由于使用了Microsoft Foundation classes，代码流程很简单，但是实现的功能比较充分



Filter.h：头文件，定义了CFilterApp 类

Filter.cpp：利用MFC的函数实现了CFilterApp

Filter.rc：资源文件，包括对话框和图标的说明-use a filter to write MFC source code, code structure is very delicate, can be functional : a fixed band-pass filtering two variable bandpass filter to delete four 3 noise input and output error calculation is relatively simple to achieve. As the use of Microsoft Foundation classes, code process is simple, but to achieve the more fully functional Filter.h : The first document, CFilterApp definition of the category Filter.cpp : MFC function realized CFilterApp Filter.rc : resource files, including dialog box and the note icon
