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 )

说明：  LabVIEW中TCP通讯需要用到的强制类型转换的使用方法(The method of TCP communication in LabVIEW)

Labview宝典课件，非常适合初学者学习的一点即通的学习资料(Labview Collection courseware, very suitable for beginners to learn the point that through the learning materials)

This paper is based on acoustic emotion recognition.Emotion recognition means recognizing human s emotional state his/her s voice through features extracted their voice.In this paper nine popular s are explained.

labview实现网络摄像头的图像采集，通过TCP/IP协议采集摄像头的图像，这是我在实际监控安防项目中用到的，绝对可以使用。(The LabVIEW realizes the image acquisition of the network camera, and collects the image of the camera through TCP/IP protocol. This is what I used in the actual monitoring and security project. It can be used absolutely.)

基于生产消费者模式的多串口采集程序，用labview进行上位机处理(Serial port acquisition program, based on the pattern of production of consumer PC processing using labview)

在labview环境下编写实现语音信号的采集播放加噪降噪和滤波功能(Under labview environment prepared to play the voice signals to achieve acquisition plus noise and noise reduction filtering)

虚拟仪器高级应用全书例子，用的C语言开发环境Labwindows/CVI，有各种高级应用的例子，非常值得学习参考。(Virtual instrument advanced application book example, using the C language development environment Labwindows/CVI, there are a variety of advanced application examples, it is worth learning reference.)

说明：  UDP基本通讯模块，可以清楚的了解labview的UDP通讯方法，而且有一定的表明(labview UDP send model is helpful for us to learn this software)

说明：  NI Style control group, which contains some style controls other than the self-contained controls, can beautify the interface style.
