数据处理

简易计算器，实现加、减、乘、处、开方等功能。(Simple calculator to add, subtract, multiply, at the square root function.)

FFT，包络解调，共振解调，包络检波，倒频谱的labview的程序，这些都是我自己编的，不是从论坛下载的(FFT, envelope demodulation, envelope demodulation, cepstrum, demodulated resonance)

labview自动、自定义保存界面参数简单子VI(labview automatically, simple custom save the interface parameters 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.)

任意信号的时频分析仪，包含傅里叶变换和功率谱图等分析。(Any time frequency analyzer based on LabVIEW)

对LabVIEW进行二次开发，对信号进行聚合经验模态分解。(The LabVIEW is developed two times, and the signal is aggregated by empirical mode decomposition.)

说明：  基于LabVIEW数据库的操作教程，内含全面的ADO对数据库的全面操作，简单易懂。(Database reference tutorial)

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.)

该vi主要是一台简单的单通道数字示波器，实现数据采集、波形显示、信号处理、波形存储等(The main vi is a simple single-channel digital oscilloscope, data acquisition, waveform display, signal processing, waveform storage, etc.)

实现labview的pwm控制，产生占空比可调的PWM波形(Labview realize the pwm control, adjustable duty cycle of the PWM waveform generated)
