Signal power spectrum based on FFT

输入字符串 生成相应的CRC16-modbus校验码(create the crc16-modbus checkcode depends on the charactor string input to the program)

基于labview信号采集的源程序，对于初学者有一定帮助(Please enter text to be translated is based on the labview source program signal acquisition, it is helpful for the beginner to content )

labview与机械手的九点标定 手眼标定的实现(LabVIEW and nine-point calibration of manipulator)

机械振动信号的自相关分析，对其进行周期成分检测(Autocorrelation analysis of mechanical vibration signals to detect its periodic components)

实现labview 虚拟双踪示波器的波形显示和波形叠加，以及波形参数测量和保存，另外还可以保存波形的点的数据，并可以利用保存的.lvm文件实现波形回显。外加一个简单的滤波器程序。(It realizes the waveform display and waveform superposition of LabVIEW virtual double trace oscilloscope,and the measurement and preservation of waveform parameters.In addition, it also saves data of waveform points, and can save waveform data by using saved.Lvm files. Add a simple filter program.)

Labview下面开发的一个用ActiveX操作Excel的例子，写的比较规整，需要使用LabVIEW2011及以上版本打开。内部有12个vi和完整的工程文件，可以直接打开工程文件运行。经过调试，确保可以正确运行。(An ActiveX example for excel operating based on LabVIEW.)

说明：  该文件是labview实现例子，写入和读取二进制文件。(This file is an example of LabVIEW implementation, writing and reading binary files.)

labview中用程序去产生一个触发事件是个难点，相关的介绍和例子并不多，本程序使用值属性信号结点改变的方法去产生一个事件，实现程序控制产生触发事件的功能，labview开发版本8.2。(labview using the program to generate a trigger event is difficult, relevant examples of the introduction are not many,here we use the value change of the node attribute of the signal to generate an event, the realized the program control functions to generate trigger events, the version of labview development is 8.2 .)

labview工具,通过IP向服务器发送UDP数据,验证IP接口的传输能力.安装在客户端,具有用户输入界面, 输入通讯IP地址和数据抽样位数.(This is a labview tool, it send UDP data to server by IP network, to vverify the capability of IP transmission. it is installed in client, input parameter is server IP address and sample number)

很实用的窜口数据采集系统 版本：labview8.5(Very practical channeling port data acquisition system version: labview8.5)
