Spectrum Analysis

里面包含了labview2016版本所有模块的下载链接(It contains a download link for all the modules of the labview2016 version)

通过Labview编写的基于Thought Technology公司开发的EEG采集设备的脑电数据采集程序。(By Labview prepared based on EEG developed by Thought Technology EEG data acquisition equipment acquisition program.)

串口读写，基于labview做的，可以实现上位机与下位机调试用(Serial reading and writing, based on labview do, you can achieve the PC and the next crew debugging)

周立功canpro-II的源代码。学习下(Week canpro-II source code. Under study)

本设计采用NI PCI-6221数据采集卡，运用虚拟仪器及其相关技术于多通道数据采集系统的设计。该系统具有数据同时采集、采集数据实时显示、存储与管理、报警记录等功能，最后使用Web技术实现了采集数据的远程访问(This project use NI PCI-6221 DAQ(data acquisition) card,ingeniously applyes VI technology in the development of a Multi-channel data acquisition develoment and finally achieves a solution which can provide many functions including multi-channel and multi-parameter signal acquisition,huge measurement information storage and management,Alarm record, and Collecting data show that real-time.Finally the use of Web technology to achieve the Acquisition of data remote access.)

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.)

串口测试，labwindows经常用到。这个代码比较简单直观实话初学者。(rs232 com)

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )

方根幅值是计算裕度指标与波性指标的必要部分，本文件将其独立做成了一个子VI，方便labview程序调用。希望对小伙伴有所帮助！(The root mean square amplitude is a necessary part of the margin index and the wave index. This document makes it a sub VI, which is convenient for LabVIEW program call. Hope to help small partners!)

基于labview的简单变声程序，简单而有趣，可以尝试一下，并做出改进(Labview program based on a simple change of sound, simple and fun, you can try and make improvements)
