这是简易的FSK信号调制，把文件放入matlab的文件库中，通过在matlab的命令窗口直接调用功能函数并运行，可以直接看到仿真结果。(This is a simple FSK signal modulation, the file into Matlab file library, call function directly in the Matlab command window and run the simulation results can be seen directly.)

ERA是一种对结构进行试验模态参数识别的方法，这是一种时域识别的程序(ERA is a method for identifying modal parameters of structures, which is a program for time domain identification.)

说明：  根据RGB图像创建一幅灰度图像二值图像的取反操作(RGB image created in accordance with a gray-scale images from binary images of the anti-operation)

用双线性变换法设计BW型或CB型的不同类型（低通、高通、带通）的数字滤波器求出系统的单位脉冲响应h(n)(Bilinear transform design BW or CB-type (low pass, high pass, band-pass) digital filter to find the system unit impulse response h (n))

关于matlab的一些程序，比如各种滤波器设计(some program about matalb,such as kinds of filter s design)

生成一个采样频率2000，由50Hz、120Hz、200Hz正弦信号以及噪声信号组成的数字信号，滤掉150Hz>f>100Hz的频率，计算并显示滤波前后的原始数据波形以及功率谱密度。(A sampling frequency of 2000, a digital signal composed of 50Hz, 120Hz, 200Hz sine and noise signals, is generated to filter out the frequency of 150Hz>f>100Hz and to calculate and display the original data waveforms and the power spectral density before and after the filtering.)
