Sound-level-measurement

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 )

用labview开发的服务器端tcp/ip通讯程序,可用于工业控制中的网络通讯部分(Using LabVIEW to develop server-side tcp/ip communication procedures, can be used for industrial control of the network communication part)

说明：  Labview Call Matlab 测试Labview调用Matlab脚本(Labview Call Matlab Test Labview to call Matlab script)

普源DS1000系列示波器labview RS232和GPIB通信驱动.(this is labview driver for Rigol DS1000.)

Stanford Research 830 Acquire Measurement 用于锁相放大器的单个参数，多个参数，多点的测量(Stanford Research 830 Acquire Measurement for single parameter, multiple parameter, multi-point measurement for PLA)

说明：  改程序实现的是一个扫频仪，里面包含了几个小程序(Reform program implementation is a Sweeper, which contains several small programs)

说明：  通信原理各种模拟信号的调制仿真，包括AM、FM、2DPSK等调制的仿真。(Modulation simulation of various analog signals in communication principle, Including AM, FM, 2DPSK modulation simulation.)

用LabVIEW编写，从excel中读取数据到labview中，将labview数据存储到excel中 这个比较简单了，直接利用写入电子表格文件VI。(Write in LabVIEW, read data from Excel to LabVIEW, store LabVIEW data into Excel This is a simple way to write directly to the spreadsheet file VI.)

Labview的3D控件的功能介绍，还有三个例子程序：陀螺仪，2D魔方，3D魔方。(Function Labview 3D controls introduction, there are three examples: gyroscope, 2D Rubik' s Cube, 3D cube.)

通过Labview编程实现服务器上传和下载资料(Through Labview programming server upload and download information)
