本程序用于测试实时时钟模块SD2000的SRAM存储器D/E系列， 程序功能如下： 1. 关闭/INT1及/INT2的中断输出 2. 初始化时间(写时间数据) 3. 在BREAKPOINT1设断点时,依次读时间-写SRAM数据-读SRAM数据循环 4. 全速执行时,LED四位分别显示小时和分钟的值-procedures used to test the real-time clock module SD2000 SRAM memory D/E Series, procedures following functions : 1. Closed/INT1 and/INT2 the interruption of output 2. Initialization time (the time to write data) 3. Located in BREAKPOINT1 breakpoint, followed by time for-write SRAM data-reading cycle of four data SRAM. full speed of implementation, respectively, four LED display hours and minutes values

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。-constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.

C# GetMachineIP 获取本机IP的源码，实现步骤：定义一个变量，用来记录IP地址,System.Net.IPAddress[] addressList = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList;//获取IP地址列表,然后遍历IP地址列表，获得遍历到的IP地址，最后显示IP地址。
