并查集

一个用LABVIEW构建的数据采集的例子，很好的，一起学习。-Used to build a LABVIEW data acquisition examples of very good to learn.

说明：  模式网站，有需要的自行下载，虽然有点老，一样不错(Model website, need to download, although a little old, as good as)

说明：  内置麻雀搜索算法优化支持向量机的程序，还有麻雀搜索算法提出的原论文(Built in sparrow search algorithm to optimize the support vector machine program, as well as sparrow search algorithm proposed in the original paper)

对一系列散点数据进行拟合，得到平滑的曲线(A series of scattered data are fitted to obtain a smooth curve)

说明：  利用小波包变换可以实现对信号消噪处理，让被噪声覆盖的信号更明显的观察出来。(Wavelet packet transform can be used to denoise the signal and make the signal covered by noise more obvious.)

一个很菜的遥控接收程序，可以检测用户码，请各位哥哥多指导！-a very remote receiver dishes procedure can detect user code, please guide more you brother!

说明：  滤波反投影算法，基于python编写小巧方便你值得拥有啊啊啊啊啊啊啊啊啊啊啊啊啊啊(Filtered back projection)

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.)
