Description: 现有一个信号：x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的：
低通滤波器，滤除cos(2*π*n/3) 的成分，即想保留的成分为1+cos(π*n/4)
高通滤波器，滤除1+cos(π*n/4) 的成分，即想保留的成分为cos(2*π*n/3)
带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4)
带阻滤波器，滤除cos(π*n/4) 的成分，即想保留的成分为1+cos(2*π*n/3)
1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器；画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。
-an existing signal : x (n) = a cos ( * n / 4) cos (2 * * n / 3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2 * * n / 3) the ingredients that want to retain an element of a cos ( * n / 4) high-pass filter, a filter cos ( * n / 4) components, namely to retain the element of cos (2 * * n / 3) band-pass filter , a filter cos (2 * * n / 3) components, namely to retain the element of cos ( * n / 4) band stop filter, the filter cos ( * n / 4) components, namely to retain the ingredients for a cos ( 2 * * n / 3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).

Description: Character Recognition Using Neural Networks
Steps to use this GUI.
1. Open the GUI figure, run it. (accept the matlab to change its directory to new location where the file is stored)
2. First we need to teach Character to computer. For this type the Character in the textbox space provided and press \"TEACH\".
3. You can save all the taught data.
4. For retrival, click start.
Note: Paint Brush software of microsoft opens for entering the image. So, we need to save the image after editing.
For best results teach each Character not less than ten times.

Description: BPSK.m是使用蒙特卡罗仿真验证能量检测法，效仿文献中的图1。
由于运算量大，建议不运行程序，运行时要耐心等待。
该程序得出的图见n=10000.fig文件，但由于与图1不是很像，建议
论文图片附上SNR.m（理论计算画图程序）运行后的图片，程序可用BPSK.m。
T2-T6.m根据文献理论计算得出的程序，效仿文献中的图2-6，
暂时没有进行蒙特卡罗仿真。
-BPSK.m using Monte Carlo simulation of energy detection, follow the example of Figure 1 in the literature.
The large amount of computation, it is recommended not to run the program, run-time to wait.
The program plans drawn to see the n = 10000.fig file, but Figure 1 is not much like, it is recommended that
Paper picture to attach SNR.m (theoretical calculation of the Paint program) running pictures, program available BPSK.m.
According to theory, T2-T6.m calculated program, follow the example of Figure 2-6 in the literature,
