这里　提供了　罗克韦尔ｌｏｇｉｘ５０００的各种指令集，是利用罗尔韦尔自动化控制者的一个不错的小工具　可以随时查阅这些指令(Rockwell logix5000 here provides a variety of instruction set, is the use of automated control Luoerweier' s a nice little tool to gain access to these instructions)

要求：从x(t)=sin(2*pi*5*t)+sin(2*pi*200*t)+sin(2*pi*50*t)信号中滤出频率为5Hz的信号(Requirements: from x (t) = sin (2* pi* 5* t)+ sin (2* pi* 200* t)+ sin (2* pi* 50* t) signal to filter out the signal frequency of 5Hz)

维纳滤波matlab仿真程序。 维纳滤波matlab仿真程序。(Wiener filter matlab simulation program)

it is used seperate framses from an video and to extract as jpeg images

“RADAR SIGNAL ANALYSIS AND PROCESSING USING MATLAB”。matlab对雷达信号的分析与处理（英文版），是学习处理雷达信号的入门教材。主要内容有雷达系统原理介绍和常用matlab函数。(" RADAR SIGNAL ANALYSIS AND PROCESSING USING MATLAB" . is a primary book of radar signal processing. The main contents is introduction of radar systems and some matlab functions.)

重力异常的向上延拓程序，很实用，，推荐地球物理学生学习可直接使用。 (Gravity anomaly upward extension program, it is practical, and recommended geophysics student learning can be used directly.)

c# GUI+ 多种仪表盘，很难找的仪表盘，也很实用(c# GUI+ variety of dashboard, it is difficult to find the instrument panel, but also very practical)

说明：  selective harmonics elimination

说明：  基于ziegler-nichols方法的pid整定，包括连续与离散两种方法，是基于稳定性分析的pid整定方法。(based Ziegler-Nichols pid of the whole, including both discrete and continuous method is based on analysis of the pid stability of the entire system.)
