序列信号发生器:
在系统时钟的作用下能够循环产生一组或多组序列信号的时序电路,(循环产生一组序列信号0111010011011010)
序列检测器:
检测一组或多组又二进制码组成的脉冲序列信号,当序列检测器连续收到一组或多组序列信号,如果与预先设置的码11010相同的时候,输出1,否则输出0.

整个系统分为两个模块:检测模块和解码模块。检测模块主要完成从输入串行序列判断出A,B或C信号,并分别输出脉冲标志脉冲串Signal_A,Signal_B和Signal_C;同时,当检测到任一信号时,BIT_EN_temp输出一个高脉冲。解码模块根据检测模块输出的三个标志脉冲进行0/1解码,输出最终的密勒解码数据DOUT;同时,输出DATA_EN和BIT_EN两个标志信号。-The whole system is divided into two modules: detection module
