利用MATLAB和labview混合编程实现小波降噪。(Using MATLAB and labview hybrid wavelet noise reduction by programming. )

一本很不错的英文LabVIEW书籍，详细阐述了labview的设计思想和范例。(a very nice book talking about how to design a good LabVIEW program.)

说明：  可以通过labview进行USB通讯，凄凄切切群群群群群群群群群(USB communication through LabVIEW)

基于labview的modbus通讯范例(Modbus communication paradigm based on LabVIEW)

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

说明：  噪声检测，声卡采集，频率分析，数据统计分析，均方根(Noise detector,Sound card acquisition,frequency analysis,Statistical analysis of data,Root mean square)

说明：  不规则边界单个圆的拟合功能，在原先图片的基础上画近似圆(Fitting function of single circle with irregular boundary)

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)

本文主要介绍了利用国产普通数据采集卡，基于美国 NI 公司提供的虚拟仪 器软件开发平台 LabVIEW 和实验室原有发动机硬件平台自行开发的一套气缸压 力采集模块和数据分析模块(This thesis primarily introduced software about cylinder pressure and crank angle acquisition and data analysis module. It is designed by using a general data acquisition board, which is based on Virtual Instrument LabVIEW offered by NI and laboratory engine. )
