这是一个在ＶＣ环境下实现动态图形变化的例子，里面包含各种类型的曲线图，相信对学习用ＶＣ画图功能的读者会有很大的帮助(This is a VC environment in the realization of dynamic graphics examples of changes, which contains various types of curves, I believe that learning to use drawing functions VC readers will be of great help)

这个是一个自己做的程序，可以进行相关的操作，初学者(This is a program to do their own, can be related to the operation, for beginners)

实现枚举设备的功能，像window设备管理器一样的功能。简单使用，解决了很多程序员的苦恼问题(The achievement of enumerated devices, such as Device Manager window functions the same. Simple to use, a lot of programmers to solve the problem of distress)

c++程序设计讲义 cppprograming 含源码(c++ programming including lectures cppprograming source)

由设计要求可知，wp<=0.2π，允许误差幅度小于1dB，ws>=0.3π内衰减应大于15dB。为了验证数字滤波器的实际滤波功能，设计程序时，把输入序列定为验证函数x（t）=4sin（100πt）以及x（t）=4sin（200πt）和x（t）=4sin（400πt）。又因为Ts=1.25ms，T=80ms，故采样点为64，即N=64，所以当M=6，可以同时调试并验证程序的滤波功能。(Seen by the design requirements, wp < = 0.2π, allow a margin of error of less than 1dB, ws> = 0.3π within attenuation greater than 15dB. In order to verify the actual filtering function of the digital filter design program, the input sequence as validation function x (t) = 4sin (100πt) and x (t) = 4sin (200πt) and x (t) = 4sin (400πt) . And because Ts = 1.25ms, T = 80ms, so the sampling points is 64, that is N = 64, so when M = 6, can debug and validate filtering program.)

这是IIR数字滤波器的设计及滤波程序，IIR滤波器用matlab实现，滤波数据用C生成，主程序实现数字滤波(This is the IIR digital filter design and filtering procedures, IIR filter using matlab, using C to generate filtered data, the main program to achieve digital filtering)
