基于labview的虚拟波形发生器，能够实现正弦、余弦、锯齿波的产生(Labview-based virtual waveform generator, to achieve the sine, cosine, sawtooth generation)

说明：  通过CCD识别目标的形状，可供学习视觉编程参考(Identifying the shape of the target by CCD can be used as a reference for learning visual programming.)

LABVIEW 小波变换求波峰，对比传统方法与小波方法的优缺点(LABVIEW wavelet transform for wave crest, comparing the advantages and disadvantages of the traditional methods and wavelet methods)

右键菜单功能，LabWindows实现的，使用弹出菜单(Right-click menu, LabWindows achieve)

Labview基于声卡的频谱分析 声卡采集声音数据,显示其波形,通过滤波器和加窗处理进行功率谱分析(Labview based sound card spectrum analysis Sound card data collection, display its waveform, through the filter and window processing power spectrum analysis)

再LabVIEW中实现MySQL功能调用的模块，动态链接库，实现在labview中进行数据库管理(MySQL function module called again in LabVIEW, dynamic link library in labview database management)

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.)
