Labview设计虚拟信号发生器

本文介绍了如何运用lABVIEW软件进行故障诊断监测(This article describes how to use LabVIEW software to troubleshoot monitoring)

labview程序，需要DBC读取CAN信号,同时也能读取NI设备的信号(read and write the signal form CAN bus.)

这是使用Labview实现I2C通讯的程序，很好的算法，通讯速率会很快。(This is the use of Labview realize I2C communication procedures, a good algorithm, communication speed very fast.)

用LABVIEW做的串口通讯无线温度（DS18B20）采集系统，可以实现对温度数据的采集，波形显示，报警，数据回放和数据保存功能。程序简单易懂，送给有需要的同学学习~(Serial communication using LABVIEW to do wireless temperature (DS18B20) acquisition system, you can achieve the acquisition of temperature data, waveform display, alarm, data playback and data retention. Program is easy to understand, give students need to learn ~)

labview tcp经典的编程示例可以帮助大家参考学习(LabVIEW TCP classic programming examples can help you learn from the reference.)

labview调用dll实现QR二维码生成，包含dll说明等，可作为子vi直接使用(LabVIEW calls the DLL implementation of QR code generation, including DLL, can be directly used as a sub VI )

LABVIEW初学练习，定点数转换，了解VI的创建，保存以及前面板和程序框图(LABVIEW Initial Practice, Fixed Point Conversion, Understanding VI Creation, Preservation and Front Panel and Program Block Diagram)

利用NIUSRP 和LABVIEW数字通信实验平台，进行信道估计和信道均衡，实践均衡器的原型设计和性能评测。(Use LABVIEW and NIUSRP digital communications test platform for channel estimation and channel equalization, practice equalizer prototyping and performance evaluation.)

基于labview平台的虚拟示波器，能实现基本的示波器功能。(The virtual oscilloscope based on LabVIEW platform can realize the basic oscilloscope function.)

用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )
