线路码 Line code
（重定向自Line encoding）
线路码（英语：Line code），有时也称传输码。为了便于数字信号传输，将原始的数据码进行一定的修改就得到了线路码。举例来说，当原始数据中存在长时间连续的1或0时，接收方便很难得知每一位信号的时长，也可能误以为信号传输终结而中断通信。线路码还可增加纠错功能，适应信道的特性。常见的线路码包括AMI码、HDB3码等。

In telecommunication, a line code is a code chosen for use within a communications system for transmitting a digital signal down a line. Line coding is often used for digital data transport. Some line codes are digital baseband modulation or digital baseband transmission methods, and these are baseband line codes that are used when the line can carry DC components.
