C#中调用VC++的DLL
[DllImport("diaCallBackDll.dll")] public static extern void show(); [DllImport("diaCallBackDll.dll", CallingConvention = CallingConvention.StdCall)] public static extern int add_CallBack_test(int a, int b, cb_func f); public static void cb_funcc(int re) { Console.WriteLine("result=[{0}]", re); return; } static void Main(string[] args) { //show(); int i = add_CallBack_test(7, 2, cb_funcc); Console.Read(); }

:滤波
fs=400 采样频率,必须大于两倍基带信号最高频率
ts=1/fs 采样时间间隔
T=5 时间窗大小
t=0:ts:T (hf1=zeros(1,N)
hf1(f<=B1&f>=-B1)=1
y1=hf1.*fftshift(y)
figure
subplot(211)
plot(f,abs(fftshift(y))/N,f,hf1, r-- )
axis([-fs/2,fs/2,0,1.2])
title( 原信号频谱 )
xlabel( f /Hz )
subplot(212)
plot(f,abs(y1)/N)
title( 低通滤波,截止频率90Hz )

大家都认为用SDK做非常难,就是建立框架然后再对框架进行消息处理。 跟Windows自带的计数器很类似,在这里和各位WIN32 SDK爱好者交流交流。(We all think that is very difficult to do with the SDK is to establish a framework and then right framework for message processing. Windows comes with a counter is very similar to VC lovers here and you exchange exchanges.)
