Manchester码的编码规则是，如果原始数据为“1”，将其编码成“10”；如果原始数据为“0”，将其编码成“01”。这种编码的特点是每个码元中间都有跳变，低频能量较少，便于接收端提取时钟信息。-Manchester, the coding rule is, if the original data is " 1" , be coded " 10"　 if the original data is " 0" , be coded " 01."　This code is characterized by the middle of each symbol has a jump, low energy less easy to extract the clock information on the receiving end.
