语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

说明：  使用信号的Higuchi分行维数提取出信号的暂态特征(Using Higuchi Branch Dimension of Signal to Extract Transient Characteristics of Signal)

pid和GPC算法的结合，通过两种算法的结合，相互补充。(pid and GPC algorithm combined, through a combination of two algorithms complement each other.)

一种计及不完备信息的电力系统抑制弧Petri网故障诊断改进模型，保证在出现保护、断路器发生误动、拒动或者警报信息出现丢失、畸变等异常情况时的故障诊断结果的准确性(An account of incomplete information systems inhibit electrical arc Petri nets improved fault diagnosis model, to ensure that in the event of the protection circuit breaker malfunction occurs, tripping or alarm message is lost, the accuracy of fault diagnosis distortion and other anomalies when the)

常用信道的实现原程序代码,可以用于通信系统性能的评估.(Original Program of the common channel)

matlab扩展编程，系统的介绍了matlab扩展编程的用法和注意细节，对matlab的继续学习打下坚实的基础。(matlab extension programming, the system introduces the use of matlab extension programming and attention to detail, to the matlab' s continue to learn to lay a solid foundation.)

说明：  用java实现的UFO攻击游戏，里面有代码和可执行文件，操作简单，用鼠标左键单击UFO， 每击落10架之后，就会增加一架。(used to achieve the UFO attack game, and they code and executable files, simple operation, using the left mouse button click UFO, each downed 10, will be an increase.)
