这是一个拉普拉斯系统分析仿真的Systemview源代码。-This is a Laplace System Simulation Systemview source code.

We have to design a second order Butterworth filter having a sampling frequency of 20 kHz and -3db cut of frequency at 2 kHz in visual C. Only low frequency signals can pass through this filter and the signals having the frequency higher than frequen

拉普拉斯分布的函数，官方的，我用了很好，产生一定分布的角度-Laplace distribution function, the official, I used a very good

三种滤波器对图形处理，拉普拉斯滤波器，反锐化掩模滤波器，高提升滤波器等-Three kinds of filters for graphics processing, Laplace filter, Unsharp Mask filter, high-enhancing filters, etc.
