锁相技术在测控、通信、数字信号处理等众多领域得到了广泛的应用。虚拟锁相环成为锁相环发展趋势之一，根据锁相环路的基本组成及原理，利用LabVIEW软件提供的强大的数值计算和信号分析等能力对锁相环进行设计。实验和仿真结果表明该软件锁相环具有较好的捕获和跟踪性能。利用软件实现的锁相环比硬件锁相环具有更好的灵活性和通用性，同时具有结构简单、参数设计灵活等优点。(Lock-in technique in many areas of monitoring and control, communications, digital signal processing, has been widely used. Became one of the virtual phase-locked loop phase-locked loop trends, according to the basic principles of composition and phase-locked loop, using LabVIEW software provides powerful numerical calculation and signal analysis capabilities such as phase-locked loop design. Experimental and simulation results show that the software PLL has a better acquisition and tracking performance. Use of software than hardware locked loop PLL has better flexibility and versatility, but also has a simple structure, flexible design parameters, etc..)

基于labview的TCP客户端程序发送主机通常将发送缓冲区中的数据按内存地址从低到?的顺序发出,接收主机把从?络上接到的字节依次保存在接收缓冲区中,也是按内存地址从低到?的顺序保存。 TCP/IP协议规定,?络数据流应采??端字节序,即低地址?字节。 socket API是?层抽象的?络编程接?,适?于各种底层?络协议,如IPv4、 IPv6,以及后?要讲的UNIX Domain Socket。(Based on the TCP client program to send the host LabVIEW will usually send buffer according to the data in the memory address from low to order issued, the receiving host to receive from the network bytes on sequentially stored in the receive buffer, and according to the memory address from low to preservation order. The TCP/IP agreement, network data flow should be endian, low byte address. Socket API is layer abstract network programming interface, suitable in various underlying network protocol, such as IPv4, IPv6, and UNIX Domain Socket to say.)
