Four-FSK

本人做的一个计算动力学的 小作业 中心差分法(I make a calculation of the dynamics of small operations center difference method)

一个简单的四则运算考核小程序,采用VB开发。(A simple arithmetic evaluation applet development using VB.)

说明：  寻找数对，所谓数对，即a+b与a-b都是自然数的平方(find a few right, a few so-called right, and that is a a b-b is the square of the number of natural)

4-FSK信号的生成，用于数字通信原理的基础知识的学习，随机产生4fsk信号，并分析信号的频谱(Generating 4-fsk signal and spectrum analysis)

说明：  根据地层参数通过简化佐普利兹方程求取反射系数，制作合成地震记录，从而显示不同地层模型的AVO响应。(In accordance with formation parameter equation by simplifying佐普利兹find reflection coefficient, the production of synthetic seismograms, which show different stratigraphic model AVO response.)

一个小网页浏览器，很好用的，如果可以讨论一下也行(A small web browser, the good, if you can talk about is also OK)

Sample in VB for the Spacemouse Classic, you can get the status for buttons and position.

利用PSO粒子群搜索算法,辨识PID参数:Kp,Ki,Kd.结果表明虽然该方法辨识精度不是很高,但是也有一定可信度.(Use english PSO Particle Swarm algorithm, identification of PID parameters: Kp, Ki, Kd. The results show that although the method is not very high recognition accuracy, but it also has a certain credibility.)

多功能时刻钟，整点报时，还有闹钟的功能，还有些功能没有完善。(Multi-time clock, the whole point of time, as well as alarm clock function, and some feature is not perfect.)

Extended the function of the message box
