可变增益放大 程序是keil mdk 5 stm32单片机(The variable gain amplifier program is keil MDK 5 STM32 single chip computer)

减少频谱泄漏，通常在采样后对信号加窗。在电机故障诊断领域，需同时考虑频率分辨率和频谱泄漏。应用最广泛的窗函数是汉宁窗。(To reduce the spectrum leakage, a window is usually added to the signal after sampling. In the field of motor fault diagnosis, frequency resolution and spectrum leakage should be considered at the same time. The window function is the most widely used Hanning window.)

对全息图进行二维恢复以及三维形貌恢复以及最大熵阈值分割(Two dimensional reconstruction of hologram and 3D shape recovery and maximum entropy threshold segmentation are performed.)

音频采集分析，在车型声音和振动信号特征研究中的应用。 音频采集分析，在车型声音和振动信号特征研究中的应用。(Audio acquisition and analysis, sound and vibration signals in the model characteristics of the application. Audio acquisition and analysis, sound and vibration signals in the model characteristics of the application.)

用MATLAB绘制voroni图，随机产生点数，边界区域可调。(Using MATLAB to draw voroni diagram, the number of points is generated randomly and the boundary area can be adjusted.)

说明：  基于高阶累积量来实现调制信号识别，包含了matlab中用于高阶累积量的工具包(Modulation signal recognition based on higher-order cumulant)

前端加载视频，是一种很麻烦的事情，不管怎么查找都是一些无用的带吗，这里提供有用的代码参考。(Front-end loading video, is a very troublesome thing, anyway, search is some useless tape, here provides useful code reference.)

等高线拟合源代码（matlab源码），老外编的，水平确实可以，佩服。里面注释挺详细了。(contour fitting source code (Matlab source), a foreigner series, level really can admire. Inside Notes quite detailed.)

说明：  通过ETHERNET建立SIMATIC NET OPC 服务器与PLC 的S7连接(agsrjt7glohy8uihjnkvhmjfukydt5erfuygt7lo86o8lio)
