轨道FSK信号发送的小函数。这个函数虽然少，但却是在无数可行方案中选的最优，性能最佳的。在这基础上进行信号处理很不错的。(FSK signal sent from the track a small function. This function, though a small, but they are numerous options in the optimal choice, the best performance. In this based on the signal processing is very good.)

这个是我改进了的语音处理里面的端点检测源程序，可以直接编译运行，效果比较好(This is my improved speech endpoint detection treatment inside source, the compiler can be run directly, the effect is better)

Helmholtz方程的有限元解法，可以任意加密网格剖分，求解结果用图像显示.(Helmholtz equation finite element method, you can encrypt arbitrary mesh, the image display solution results.)

matlab实现的L-M算法的函数拟合，可以用了进行函数的拟合(matlab implementation of the LM function fitting algorithm can be used for the fitting function)

fastica用于信号处理，好用的工具包(FastICA for signal processing, use the toolkit)

about liftinh in matlab

An Antenna is a transducer, which converts electrical power into electromagnetic waves and vice versa.

说明：  用双线性变换法设计一个Butterworth低通滤波器，要求其通带截止频率100Hz，阻带截止频率200Hz，通带衰减小于2dB，阻带衰减大于15 dB，采样频率为500 Hz。(Using bilinear transformation to design a Butterworth low-pass filter, requiring that their pass-band cutoff frequency 100Hz, stopband cutoff frequency 200Hz, pass-band attenuation is less than 2dB, stop-band attenuation greater than 15 dB, a sampling frequency of 500 Hz.)
