本文简述了通用逻辑门ULG_n的引入思想与定义.作者同意Hurst的看法,认为有实用价值的ULG_n应是n=2、3.在综合对ULG_2与ULG_3的最新研究的基础上,作者认为文献〔12〕中提出的最佳ULG_2有可能被采用于实际电路.因此,较为系统地探讨了它在组合电路设计乃至在ROM中的各种应用.此外,本文还把通用逻辑门的概念推广,从而引出通用触发器的概念,并讨论了最佳ULG_n在设计时序电路中的应用. In this paper, we briefly introduce the idea and definition of generalized logic gate ULG_n.The author agrees with Hurst that ULG_n should be n = 2,3 with practical value.On the basis of the latest research on ULG_2 and ULG_3, The best ULG_2 proposed in [12] may be applied to the actual circuit, so it has been systematically discussed in various applications of combinational circuit design and even in ROM.In addition, this article also generalizes the concept of general logic gate, Thus leads to the concept of general-purpose flip-flop, and discusses the application of the best ULG_n in the design of sequential circuits.
