正弦信号叠加噪声SNR

显示了对labview中FFT频谱、频响、和频谱测量三个vi的区别。(Shows the difference for labview in FFT spectrum, frequency response, and spectral measurements three of vi.)

利用labview编程和数据库连接起来，实现对数据的存储与读取(ligner with labview)

使用labview实现中断访问串口，使用消息队列方式传递数据。(Use labview realize interrupt visit, use the message queue serial port style to deliver data. )

基于转速环-电流环双闭环控制的直流电机调速系统的labview上位机程序。(The LabVIEW upper computer program of DC motor speed control system based on double closed-loop control of speed-loop and current-loop.)

说明：  一个简单的声音采集系统，有声音采集和声音回放功能，还可以将采集到的声音在时域频域进行分析(A simple voice acquisition system has the functions of voice acquisition and playback. It can also analyze the collected voice in time domain and frequency domain.)

说明：  本Demo演示了NI公司LabVIEW图形化开发环境的并行编程模式。在并行循环之间可以通过队列或者是局部变量传递数据。(This Demo demonstrates the parallel programming model of NI's LabVIEW graphical development environment. Between parallel loops, data can be passed through queues or local variables.)

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)

labview串口接收、发送（分开）程序以及总通信程序(LabVIEW serial port receive, send (separate) program and general communication program)

黑白棋程序，labview程序设计与应用一书中的应用实例(Othello program, the labview program design and application book application instance)

通过串口读取数据，利用示波器实现波形的显示，同时具有保存数据，回放图形的功能。(Read data through the serial port, use an oscilloscope to achieve waveform display, but also has to save the data, playback graphics.)
