主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。 (Main Content (signal_analyzer.rar) as follows: test1.txt the first time as t, 0.001s for the step the second as the input signal the third as the system output signal. signal_analyzer.m first test1.txt the data read into the workspace, and then FFT, the frequency of the two signals, the output amplitude for input attenuation (db), the output of the input phase difference.)

introduction of Kalman filtering

PF_KEY user interface, this is defined by rfc2367 so do not make arbitrary modifications or else this header file will not be compliant.

matlab在通信原理中的应用，TDM仿真，希望大家能用得上！(matlab in Applied Communication Theory, TDM emulation, hope that we can useful!)

说明：  控制对象P=s/s*s-1，设计了一个在D域（s:Res<-2）稳定的所有控制器C(Control object is P = s/s* s-1, designed all controllers C are stable in D filde(s:Res<-2))

可以实现全息图的一次快速傅里叶变换，对全息图进行再现，也可以用于全息干涉图的再现(Hologram can be achieved in a fast Fourier transform, reconstruction hologram can also be used for reproduction of holographic interferograms)
