Labview PID控制实验程序..供学习者参考.(Labview PID Control Experimental procedure for the learner .. reference.)

说明：  可以对单次输入的信号进行滤波分析和图像显示。同时也具备暂停和历史图像保存的功能。 本程序主要针对的是低频率的未知信号，对于高频率信号最好采用单次采样的方式。(The single input signal can be filtered and analyzed, and the image can be displayed. It also has the functions of pausing and preserving historical images. This program is mainly for low frequency unknown signals, for high frequency signals, the best way to use a single sampling.)

说明：  labview操作者架构，项目模板，面向对象编程(LabVIEW operator architecture, project template, object-oriented programming)

利用labview的xy图，画一个圆。根据sinx^2+cosx^2 1利用labview的正弦波生成函数画出圆(Use labview s xy chart to draw a circle. According to sinx ^ 2+ cosx ^ 2 1 using labview sine wave generation function to draw a circle)

示波器，基于labview平台的虚拟仪器，可以测试波形并调节幅值频率更换channel。(Oscilloscope, virtual instrument based on LabVIEW platform, can test waveform and adjust amplitude and frequency to change channel.)

说明：  labview产生波形并显示，对波形图表的曲线控制(Labview generates waveform and displays it, and controls the curve of waveform chart)

说明：  Labview汽轮机振动监测源代码，对信号进行倒频谱分析(Labview example)

说明：  用LabVIEW读取Excel数据，已使用，效果不错，教程不错。(Read the excel data with LabVIEW!)

labview利用mydaq输出正弦波，三角波，方波(LabVIEW uses mydaq to output sine wave, triangle wave, Fang Bo.)
