摘　　要：本文利用CPLD设计了一个11位的巴克码信号发生器,该发生器具有单次和连续输出功能,同时也设计出了一个11位的译码器来驱动发光二极管,当接收到巴克码时发光二极管亮,没有检测到时则发光二极管灭。In this article, an 11-bit signal generator of bark code has been designed, the function of the generator has single and continuous output, at the same time, an 11-bit encoder of bark code has also been designed to drive the LBDs, the LBDs won＇ t be light until the bark codes are taken over, otherwise the LBDs will be extinguished.

关 键 词：CPLD 巴克码 信号发生器 译码器
