IIR Filter Nth Order Implementation Code

这个matlab程序能够实现裁剪图像感兴趣区域，适合初学的。(The matlab program to achieve crop the image regions of interest for beginners.)

该文件是关于采样和量化的一些资料，对于加深采样量化概念的理解具有一定的参考价值。(The document is on the sampling and quantification of some of the information, for better understanding of the concept of sampling to quantify a certain reference value.)

说明：  国外的CIC补偿滤波器设计文件，非常有用(Abroad, CIC compensation filter design files, very useful)

不用多说了，和Hogh搭配使用检测直线的程序 直线Hough变换利用图像空间和Hough参数空间的点－线对偶性，把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计，然后在Hough参数空间寻找累加器峰值的方法检测直线。(Needless to say, Hogh mix and the use of linear detection procedures Hough transform space and the use of images Hough parameter space The point-line duality, the image space detection switch to the parameter space. Through the parameter space for a simple cumulative statistics, then Hough parameter space for accumulator peak detected straight.)

该程序可以画出三维的运动轨迹，可以看到轨迹的前视图，还可以对轨迹进行旋转等(The program can draw three-dimensional trajectory, you can see the front view of the track, the track can also be rotated, etc.)

this is the code about how to choose the best gen of the GA. it is use the roulette wheel algorithm, where the best gen will be selected randomly using this.

此文件很棒的，通过修改动力仿真软件advisor模型数据来来实现对传动系统参数的优化，可以配合相应的算法程序，如退火法，粒子群，遗传等(matlab assist parameter optimization)

实现ASK信号的调制解调 带有低通滤波器的设计(ASK )

信噪比，相对强度噪声对PAM4调制误码率的影响(Influence of signal to noise ratio on BER of PAM4 modulation)
