摘 要
利用LabVIEW建立更加简洁方便的虚拟示波仪,频谱分析仪等,产生原始信号并组成了对信号的分析处理系统。首先是对原始信号进行时域波形显示,频域频谱显示。最后再对滤波后的信号进行相关分析,引线框架除掉谐波干扰信号。最终完成对所有干扰信号的过滤。 人脸抓拍系统
虚拟仪器的出现是测量仪器发展历史上的一场革命。它充分利用最新的计算机技术来实现和扩展仪器的功能，用计算机屏幕可以简单地模拟大多数仪器的调节控制面板，以各种需要的形式表达并且输出检测结果，用计算机软件实现大部分信号的分析和处理,完成大多数控制和检测功能。用户通过应用程序将一般的通用计算机与功能化模块硬件结合起来,通过友好的界面来操作计算机,就像在操作自己定义，自己设计的单个仪器,可完成对被测量的采集，分析，判断，控制，显示，数据存储等。 虚拟仪器是一种高效用于构建数据采集与监测系统图形化编程语言。使用虚拟仪器，您快速创建用户界面，让您交互控制您的软件系统。要指定您系统的功能，您只需装配块关系图金银卡纸—一种自然的设计表示科学家和工程师。测量硬件紧密集成方便了数据采集、分析与演示文稿解决方案的快速发展。

Using LabVIEW to establish a more concise and convenient virtual oscilloscope, spectrum analyzer and so on, to produce the original signal and the composition of the signal analysis and processing system. The first is on the original signal time-domain waveform display, frequency spectrum display. Finally, the filtered signal correlation analysis, remove the harmonic interference signal. The final completion of all interference signal filtering.
The emergence of virtual instrumentation is a revolution in the history of the development of measuring instruments. It fully utilizes the latest computer technology to implement and extend the instrument function. Using the image of a computer screen can be easily simulate a variety of equipment control panels to the needs expressed in the form of the output of test results. Using computer software to achieve most of the signal of the analysis and processing to complete a variety of control and test function. The user throu能量传送器
gh the application of general-purpose computer program modules and features of the hardware together. Through friendly graphical interface to operate this computer. As in operating their own definition of individual instruments of their own design can be measured to complete the acquisition, analysis, determine, control, display, data storage and so on.
