通过对HDB3码的特殊性分析,在进行编码时引用计数器来计算两个V之间1的个数,经过4个码元后,开始判断是否插B,同时采用双向码解决了插V难的问题.最后,采用VHDL语言在Max+plusⅡ中实现了HDB3码的编码.

The design concept for encoder of HDB3 code is that firstly find the crab code "V",and make sure if the wreck code‘V'conforms to 1 or 0 in the 3rd symbol.In the meantime,make sure that there are no complement code‘B',resum 4 sequential‘0'code accordingly,substitute all‘-1'for plusl,and output encode infonmation finally.The encoding of HDB3 code can be achieved in Max+plus Ⅱby VHDL when making simulation.
