labview 语音信号采集及频谱分析的程序，功能强大好用(labview voice signal acquisition and spectrum analysis)

3σ准则 利用LabVIEW编写 剔除粗大误差(to Elimitate the gross error)

索引数据的使用，包括一些数组和单个字符等等，使用较为简便(The use of index data)

自己用Labwindows/CVI写的频谱分析仪例子程序，对开发示波器一类虚拟仪器的同学很有用。(Own use Labwindows/CVI examples of written procedures for the spectrum analyzer, oscilloscope on the development of students for a class of virtual instrument is useful.)

说明：  ?USB ADIO 八件套：LabVIEW虚拟仪器开发板 电脑USB供电，无需外部电源，2路AI，2路DI，2路DO（可驱动3.3V继电器），2路5V电源输出。可直接配合上百种传感器使用，9种自动保护措施，安全方便。无需驱动，采样率可达每通道20kHz，可在Windows XP、WIN7（32/64位）、WIN8（32/64位）、WIN10等操作系统下稳定运行，有配套的电脑软件，包含波形显示、存储、分析等十余种功能，操作简单直观。 端子定义说明 ? AI0、AI1为模拟量信号输入端子； ? DI0、DI1为数字量信号输入端子； ? DO0、DO1为数字量信号输出端子； ? 5Vo是5V电源输出端子； ? GND为公共接地端。(Eight sets of USB ADIO: LabVIEW Virtual Instrument Development Board Computer USB power supply, without external power supply, 2 AI, 2 DI, 2 DO (3.3V relay drive), 2 5V power output. It can be directly used with hundreds of sensors, 9 automatic protection measures, safe and convenient. Without driver, the sampling rate can reach 20 kHz per channel. It can run steadily under Windows XP, WIN7 (32/64 bits), WIN8 (32/64 bits), WIN10 and other operating systems. It has supporting computer software, including more than ten functions such as waveform display, storage, analysis and so on. The operation is simple and intuitive. Terminals Definition Description AI0 and AI1 are analog signal input terminals. DI0 and DI1 are digital signal input terminals. DO0 and DO1 are digital signal output terminals. 5Vo is the output terminal of 5V power supply. GND is a common ground terminal.)

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：  使用labview进行设计，里面内含粉尘采集，气压采集，温度采集，适度采集等子程序及其集合(Design with LabVIEW, which contains dust collection, air pressure collection, temperature collection, moderate collection and other subroutines and their collection)

基于LabVIEW的的BP神经网络程序，很适用于设备的故障诊断，完全采用labview编程。(Based on LabVIEW for the BP neural network programming, it is suitable for equipment fault diagnosis, full use of labview programming.)

说明：  控制转台旋转角度情况下，7路光功率计同时探测光强变化，联谊和thorlabs设备，需导入子vi。(Under the condition of controlling the rotation Angle of the turntable, the 7-channel optical power meter can simultaneously detect the change of light intensity.)

基于labview的简易计算器，能够实现加减乘除，开方求导等基本运算(Based on LabVIEW simple calculator, addition, subtraction, multiplication and division, square root derivation and other basic operations)
