合理选择线路码型有利于提高信号传输速率，减少误码率。

It is good to raise transmissibility of signal to select reasonable line code, and to reduce error code.

通过线路码型的转变平衡数字码流中的“0”和“1”码字，从而避免码流中出现长“0”或者长“1”的现象。

Through the balance of the line pattern of change in the digital stream, "0" and "1" code word, thus avoiding the emergence of a long stream of "0" or long "a" phenomenon.
