一个简陋的数独游戏，java初学者开发，用户必须安装JDK，并设置JDK环境。-A simple sudoku game!

for the just beginning learn the computer person,use DOS is boring . after known a little DOS,think dos is mysterious.this is the book introduce how to use dos deeply.

用Zerniker多项式实现波前相位屏的仿真(Simulation of wave front phase screen using Zerniker polynomials)

说明：  针对已知多频率正弦信号的频谱，设计相应的FIR滤波器(凯塞窗函数法设计低通,高通，带通滤波器，分别提取信号并绘制频域和时域曲线)按要求进行滤波。 根据已知滤波器的性能指标设计IIR数字滤波器(双线性变换法设计巴特沃斯低通IIR数字滤波器)，并对心电图信号进行滤波处理；(For known more frequency sinusoidal signal spectrum, to design the corresponding FIR filter (Kaiser window function method of designing low-pass, high-pass, band-pass filter, respectively, to extract the signal curve) and draw the frequency domain and time domain filtering according to the known filter in accordance with requirements of performance index design of IIR digital filter (bilinear transformation method to design butterworth low-pass IIR digital filter), and to filter the ecg signal)

计算序列信号相关性； 时间序列得频域相关性运算；(Calculate sequence signal correlation; The time series has a frequency domain correlation operation;)

说明：  连续波信号的模糊函数MATLAB代码，可直接运行。(The Fuzzy Function MATLAB code of CW signal can run directly.)

在FPGA上实现CAN总线SPI接口通信，使用Verilog语言(Realize SPI interface communication of CAN bus on FPGA, using Verilog language)

实现PHPSM2解密，详细说明在文件内。具体的可以百度下(Implement PHPSM2 decryption, detailed description in the file. Specific can be Baidu under)
