Signal power spectrum based on FFT

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

labview vi程序，基于版本8.2可以直接运行，,用来仿真电容充放电过程(labview vi program, based on version 8.2 can be run directly, to simulate capacitor charging and discharging process)

说明：  TCP/IP通信截取指定IP和port的数据包(packet sniffer)

水泵振动数据采集，通道设置，模数转换，三路传感器信号采集(Pump vibration data acquisition)

本文在LabVIEW和NI-IMAQ Vision软件平台下，利用通用图像采集卡开发一种图像实时采集处理虚拟仪器系统。通过调用动态链接库驱动通用图像采集卡完成图像采集，采集图像的帧速率达到25帧每秒。利用NI-IMAQ Vision视频处理模块，进行图像处理，以完成光电探测器的标定。该系统具有灵活性强、可靠性高、性价比高等优点。(In LabVIEW and NI-IMAQ Vision software platform, the use of a common frame grabber to develop a real time image acquisition and processing the virtual instrument system. Drive general-purpose image acquisition card by calling the dynamic link library complete image acquisition, the acquisition of the image frame rate up to 25 per second. NI-IMAQ Vision video processing module, image processing, in order to complete the calibration of the photodetector. The system has the flexibility, high reliability, high cost.)

使用labview进行信号分析，主要用到了傅立叶变换和小波分析，私家珍藏，互联网上其他地方是找不到的(Labview signal analysis, the main use of the Fourier transform and wavelet analysis,)

包络检波的小程序，基于labview的程序(Envelopment analysis Applets do withThe research trend of fiber-optic sensing based on BOTDR technology has been introduced with particular attention to signal processing. The sensing principle using Brillouinscattering has been analyzed and the dependences of Brillouin shift and intensity on temperature and strain have been founded.)

摘要：以实际工程为背景，介绍了在I丑bwindows／CVI环境下，基于ActiveX技术访问Microsoft Excel 2003的方法，以及创建 自动化仪器驱动器的方法。详细阐述了访问Excel具体函数的使用方法，实现了对Excel的访问。通过该工程实例，说明 了本方法具有重要的工程实用价值。(Abstract：The approach of accessing to Microsoft Excel 2003 based on ActiveX technology in LabWindows／CVI environment is intrt~ uced，in 8cN~ence，the establishments of driving scheme for automatic instruments are presented in detail．To realize the access to Excel，the operations of accessing to the real functions are intensively illustrated as wel1．Th e experiments in the real environment demonstrate that this method illustrated here is of great value for practical applications．)

基于LABVIEW的鼠标双击时间间隔的测量(Double click the time interval measurement )
