1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

该vi主要是一台简单的单通道数字示波器，实现数据采集、波形显示、信号处理、波形存储等(The main vi is a simple single-channel digital oscilloscope, data acquisition, waveform display, signal processing, waveform storage, etc.)

对于labview编程者来说，需要解析hex文件需要额外翻查许多资料，本程序为labview程序，用来解析hex文件(labview program anlysis hex file)

labview中的虚拟示波器 特别好用 建议大家使用(labview virtual oscilloscope particularly useful to suggest that you use)

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)

根据当前热敏电阻阻值，求出当前温度值。(According to thermistor resistance, find its current temperature. Just enter the thermistor resistance can be run.)

一个包络检波的Labview程序，可插入到大型得项目文件中去，便于信号的分析(An envelope detection Labview program can be inserted into a large project file to facilitate the analysis of the signal)
