曼彻斯特编码（Manchester Encoding），也叫做相位编码（ Phase Encode，简写PE），是一个同步时钟编码技术，被物理层使用来编码一个同步位流的时钟和数据。它在以太网媒介系统中的应用属于数据通信中的两种位同步方法里的自同步法（另一种是外同步法），即接收方利用包含有同步信号的特殊编码从信号自身提取同步信号来锁定自己的时钟脉冲频率，达到同步目的。
Manchester Encoding, also known as Phase Encode (PE), is a synchronous clock encoding technique used by the physical layer to encode the clock and data of a synchronous bit stream. Its application in the Ethernet media system belongs to the self-synchronization method in the two bit synchronization methods in data communication (the other is the external synchronization method), that is, the receiver extracts the synchronization from the signal itself by using the special code containing the synchronization signal. The signal is used to lock its own clock frequency for synchronization purposes. (2018-11-09, C/C++, 320KB, 下载0次)
