In addition, lowercase letters are generally used, but the class name, interface name, and the first letter of any non-initial word must be capitalized.1.1 General ConceptsN use the complete English descriptor whenever possibleN use terminolo

Manchester Encoding(Manchester Encoding), also known as Phase Encoding (PE), is commonly used for LAN transmission. In Manchester Coding, there is a hop in the middle of each bit. The hop in the middle is both a clock signal and a data signal. However, in different books, in Manchester encoding, the value of the level beat expression is different, which produces many ambiguities:
