关于labview的USRP编写的扫频信号，观察其时域和频域波形(On the sweep signal written by USRP of labview, the waveforms in time domain and frequency domain are observed.)

说明：  基于LabVIEW的数字电压表设计。 1．掌握数字电压表的基本原理和方法； 2．基于LabView设计数字电压表并实现；(Design of digital voltmeter based on LabVIEW. 1. Master the basic principles and methods of digital voltmeter; 2. Design and implement digital voltmeter based on LabView;)

Code to calculate the Fast Fourier Transform

利用labview操作者框架写的模拟串口通信，非常不错。(The analog serial communication written by the labview operator framework is very good.)

labveiw实现基带信号的幅度调制（AM），频率调制(FM)和相位调制(PM)，可以在波形图中看到调制信号和调制后信号的叠加和对比，可以看到频域波形。载波与基带幅度和频率参数均可改变。(Baseband AM/FM/PM in labview. In the vi, you ll be able to see the modulated signal in both time and frequency domain.)

A计权是分析声学信号在计算声压级的时候必须做的一个步骤，程序里解释了A计权的方法。(A weight is a step in the analysis of acoustic signals must be done in the calculation of sound pressure level, the program explained A right.)

对振动信号采集和分析，包括信号采集，时域分析，品与分析 故障定位(Vibration signal acquisition and analysis)

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.)

本文件为labview源文件，实现labview和PLC的通讯。(This document is labview source file, realize labview and PLC communications.)

Labview 电机矢量控制程序以及3-2 3-2坐标变换程序(the labview motor FOC and Park transform)
