这是Labview整体程序，功能是用来提取二次谐波信号(Extracting the two harmonic signal)

labview对信号fft变换及信噪比分析(Signal FFT transform and signal to noise ratio analysis of LabVIEW)

说明：  一个不错的自动化测试案例，可以查看编程框架和一些数据类型用法(A good automation test case)

用户自行输入所需要的频率和占空比，得到PWM波(Users input the required frequency and duty cycle to get the PWM wave.)

说明：  根据倾角仪输出信号labview实时显示曲线图像的labview程序(Real-time display of curve image based on LabVIEW output signal of inclinometer)

labview程序实例/简单的树形结构供初学者学习(labview chengxushili)

峭度指标是非平稳信号故障诊断的重要参数。峭度指标对信号中的冲击成分十分敏感，冲击成分能量越大，其峭度值就会越大，在故障诊断的时域分析中十分重要。本文件中将其独立做成了一个子vi，便于程序直接调用。(Kurtosis index is an important parameter of non-stationary signal fault diagnosis. The kurtosis index is very sensitive to the impact component in the signal. The greater the energy of the shock component, the greater the kurtosis of the signal, and it is very important in the time domain analysis of the fault diagnosis. This document will be independent of a sub VI, to facilitate direct calls to the program.)
