【摘要】 本文提出六值代数,建立五值电路三要素理论(信号、网络和负载理论),作为定量研究五值电路的数学工具。在此基础上,首先用δ展开法由五值电路功能直接推出具有复位功能的五值反相器和动态D触发器的元件级结构。然后,对五值计数器进行研究,将其划分为五种类型,并设计出电路结构简单的具有复位功能的五值移位计数器。计算机模拟验证了上述理论和电路的正确性。更多还原

【Abstract】 In order to establish the theory of three essential elements ( theory of signal-network-load ) for five-valued circuits , a six-valued algebra is presented. This theory can be used as a mathematical tool for quantitative investigating on five-valued circuits. Based on the theory, the component level circuit structures of five-valued resetting inverter and dynamic D flip-flop are deduced firstly from five-valued circuit function using δ expanded form. Then all five-valued counters are investigated and classified as five types, and a five-valued resetting shift counter with simple circuit structure is designed. Above theory and circuits are verified by computer simulations.更多还原
