ternary code

A specific class of ( d, k, q) sequences considered as a class of the input-restricted channels for constructing the ternary code for the digital magnetic recording is dis-cussed.

本文分析了一种特殊的（d，k，q）序列，它可看作是一类输入受限通道用于构造数字磁记录中的三元码。

The code used to represent information with ternary number.
