多值逻辑在电子科学技术中的应用远不如二值逻辑那么普遍,其中一个原因就是缺乏合适的、而又不复杂的存储单元。文献[2]研究了具有三轨输出的三值主从触发器,解决了上述困难。文献[3]根据目前对三值维持阻塞触发器缺乏研究这一事实,设计了一种与文献[2]对应的三值维持阻塞D型触发器。但作为一个完整的触发器系列,还需要有一种计数型的维 One of the reasons for the application of multivalued logic in electronic science and technology is far less common than binary logic is the lack of suitable and uncomplicated memory cells. Reference [2] studied three-way master-slave flip-flop with three-rail output to solve the above difficulties. According to [3], the current research on the lack of research on the three-value maintaining blocker triggers a three-value maintenance-blocking D-type trigger corresponding to [2]. But as a complete trigger family, you also need a counting type dimension
