基于LABVIEW的虚拟频谱分析仪，可以对任意信号以及采集卡采集到的信号进行频域分析，同时还加入了时域分析，使功能更为强大。(LABVIEW-based virtual spectrum analyzer can be arbitrary signals and the signal acquisition card for frequency domain analysis, and also joined the time-domain analysis, so that more powerful.)

说明：  利用 labview面向对象编写的快速排序算法，技能学习算法，又能学习基础知识(Use labview object-oriented fast sorting algorithm, skill learning algorithm, and learn basic knowledge)

labview 代码，特别适合初学者的好东西，特别是工控的孩纸(labview files good thing for beginners especially for engineering controller)

labview 计算 CRC ，通过labview 计算CRC 校验(labview COUNT CRC 32BIT LABVIEW)

LAbview采集风扇频率实现风扇转速显示，可以手自动控制风扇转速(LAbview collects fan frequency to display fan speed. It can automatically control fan speed by hand.)

labviewDSC使用OPC,可以连接PLC(LABVIEW DSC)

基于声卡的虚拟仪器示波器，通过声卡进行数据采集，再由LABview显示波形。(A virtual instrument oscilloscope based on sound card is used to collect data through a sound card, and then the waveform is displayed by LABview.)

用LABVIEW实现保存数据的功能，使数据不会没有了(LABVIEW save data, so that data would not be without)

控制三台电机，并完成转矩给定的分配，记录转速(Control three motors and complete the assignment given torque, speed record)

利用VISA去控制GPIB串口通信，最终实现与频谱仪，电源，示波器等相互之间通信(VISA to control GPIB serial communication, and ultimately with the spectrum analyzer, power supplies, oscilloscopes, and other mutual communication between)
