CIR

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )

用C++编写的xu-white模型，适合砂泥岩地层岩石物理建模，很实用(Written by C++ xu-white model, suitable for sand-shale formation rock physics modeling, it is practical)

Quadrature Phase Shift Keying is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts in 0, 90, 180, or 270 degrees

说明：  内维尔插值在很多学科都能用到，相信对大家有用！(Neville interpolation can be used in many disciplines, I believe it would be useful!)

这是有关网络互联的一个大型课程设计，应用了ospf，nat等来实现的(This is the network interconnection of a large course design, application of the ospf, nat, etc. to achieve)

本程序用来计算空心铜绕线圈（磁体）在液氮温度下的电阻，需要线圈结构，尺寸，导线截面等数据(This procedure is used to calculate the hollow copper winding coils (magnets) at liquid nitrogen temperature resistance, the coil structure, size, conductor cross-section and other data)
