实验四

简单的电子琴labview程序，利用频率播放音乐(Simple keyboard labview program, the use of frequency to play music)

二代小波包分析，能够将选择的文件进行二代小波分解，分解层数为5层(Wavelet packet analysis)

说明：  labview读取 cad dxf文档,包括圆直线线段等等(read CAD dxf include circle line)

可以对单次输入的信号进行滤波分析和图像显示。同时也具备暂停和历史图像保存的功能。 本程序主要针对的是低频率的未知信号，对于高频率信号最好采用单次采样的方式。(The single input signal can be filtered and analyzed, and the image can be displayed. It also has the functions of pausing and preserving historical images. This program is mainly for low frequency unknown signals, for high frequency signals, the best way to use a single sampling.)

Labview串口指令收发，测试可用，放心下载(Labview YART)

labview调用动态链接库相关说明文档，及调用PMAC动态链接库Pcomm32.DLL的例程(labview called dynamic link library-related documentation, and call PMAC dynamic link library routines Pcomm32.DLL)

汽车稳定性控制ESP的LabVIEW程序，经过实际验证，精度较好。(Vehicle Stability Control ESP LabVIEW program, after the actual verification, the accuracy is better.)

此程序是基于labview的tcp/ip控件设计的多功能聊天软件，类QQ，可以进行文本、图片、文件等传输，可以在局域网、广域网内进行传输，具有很好的适用性，可以进行课程设计或毕业设计(This procedure is based on the labview tcp/ip control design versatility chat software, classes QQ, can be text, images, documents, etc. transfer, can be transmitted within a LAN, WAN, with good applicability and can be curriculum design or graduation)

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)

初步使用，与获取信号，需要自己组装各子VI实现所需功能(Initial use, with the acquisition of signals, requires the assembly of each of its sub VI to achieve the desired function)
