摘　　要：通过对2-5混值编码原理、电路三要素理论和N+1值代数理论的分析,定量研究了2-5混值门电路、触发器和带进位/借位的加减法计数器,最后设计了2-5混值/十值译码电路,使计数器输出为十值信号。与以往十值电路的设计方法相比较,此设计方案具有编码效率高、供电电压低等特点。计算机模拟验证了上述理论和依此理论设计的电路的正确性。By analyzing the principle of 2-5 mixed-valued coding, the theory of three essential circuit elements and the theory of N＋l-valued algebra, the 2-5 mixed-valued gate circuits, flip-flops and up-down counters with carry/borrow bit are investigated quantitatively, the 2-5 mixed-valued/ten-valued encoder is designed in order to make the output of counter become ten-valued signal. Compared with the conventional design of ten-valued circuits, the design has the characteristics of high coding efficiency, low voltage supply, etc. Above theory and circuits based on this theory are verified by computer simulations.
