计算齿轮故障，对齿轮进行时域分析（计算时域信号的各统计特征值）和频域分析（进行傅里叶变换，计算功率谱）(analysis of the gear )

无刷直流电机M文件程序，这是从其他论坛上面找到的，很不容易啊(Brushless DC motor M File program, which is found above from other forums, it is not easy)

Matlab在脆弱水印中的应用。对matlab在脆弱水印中的应用指明了方向(Matlab in fragile watermarking application. Of fragile watermarking in matlab application specified in the direction)

自己编的一个matlab 程序，先对图像进行加噪声，然后进行滤波，再进行边缘检测(Made themselves a matlab program, the first increase the image noise, and then filter, then the edge detection)

调幅中波收音机的接收频率段为550KHz到1605KHz，中频为465KHz。调幅传输模型，对超外差式中波收音机建模(AM medium wave radio frequencies to 550KHz receiver to 1605KHz, IF is 465KHz. AM transmission model, modeling superheterodyne AM radio)

FFT简称为快速傅里叶变换，是DTF处理的一般实现方法，一维距离成像就是对差拍信号进行FFT变换，变换所得到的幅值图像横坐标为距离信息，纵坐标为幅值信息，通过一维仿真，我们可以看到目标距离相对应的幅值信息。(FFT referred to as fast Fourier transform, is DTF processing general method, a d imaging is difference from pat signal FFT transform)
