基于Labview的数字滤波器与频谱分析仪 滤波器可以选择是否打开滤波器，可显示波形，可设置滤波器参数，可测量时域、频域的参数，可保存数据、图像；频谱分析仪可显示波形，可测量频域参数(Labview-based digital filter and spectrum analyzer filter can choose whether to open the filter to display the waveform, the filter parameters can be set to measure the time domain, frequency domain parameters, save the data, images spectrum analyzer display waveform, measurable frequency domain parameters)

说明：  示波器的设计，基本上满足日常的使用。可以自动调整频率等功能(Design of Oscilloscope)

虚拟仪器Labview：FFT、采样、加窗、互相关分析仪、滤波器、谱分析、随机信号分析仪、信号发生器.exe自谱与自相关分析.exe的可执行程序(FFT, sampling, windowing, cross-correlation analysis instrument, filter, spectrum analysis, the random signal analyzer, signal generator exe autospectrum autocorrelation analysis exe executable program)

说明：  this folder contains VIs related to USRP.

在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每 条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2， △x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。 ①一个周期128点。 ②改变颜色一定要先选择曲线，然后再改变颜色。(A sine curve and a cosine curve are displayed in two different colors on the waveform Graph display. The length of the bar curve is 128 points, where the sine curve x0 =0, Delta x=1, the cosine curve x0 =2, Delta x=5. And use the attribute node to change the color of each curve through the front panel control. One cycle is 128 points. Change the color must first choose the curve, then change the color.)

labwindows gpib 例程 操作GPIB设备( labwindows gpib)

说明：  自己做了一个用labview对CRC32数据进行计算处理的Vi(I made a VI to calculate and process CRC32 data with LabVIEW)

对LabVIEW进行二次开发，对振动信号进行HHT时频分析(The LabVIEW was developed two times, and the vibration signals were analyzed by HHT time frequency)

LabVIEW确实很强大最近开始测试 Labview的3D相关的功能。 制作3D 对象，然后显示。 导入3D对象 ，然后显示。 那个 3D图是Solidework里面导出来的。主要那个格式97的。(LabVIEW is a graphical software system for developing high-performance scientific and engineering applications. LabVIEW can acquire data and control devices via IEEE-488 (GPIB), RS-232/422 and modular (VXI or CAMAC) instruments as well as plug-in I/O boards.)

说明：  利用操作者框架编写的程序，非常利于新手了解操作者框架(Programs written using the operator framework are very useful for novices to understand the operator framework)
