摘要: 通過對(duì)2-5混值編碼原理、電路三要素理論和N +1值代數(shù)理論的分析，定量研究了2-5混值門電路、觸發(fā)器和帶進(jìn)位/借位的加減法計(jì)數(shù)器，最后設(shè)計(jì)了2-5混值/十值譯碼電路，使計(jì)數(shù)器輸出為十值信號(hào)。與以往十值電路的設(shè)計(jì)方法相比較，此設(shè)計(jì)方案具有編碼效率高、供電電壓低等特點(diǎn)。計(jì)算機(jī)模擬驗(yàn)證了上述理論和依此理論設(shè)計(jì)的電路的正確性。Abstract: By analyzing the principle of 2-5 mixed-valued coding, the theory of three essential circuit elements and the theory of N+1-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.
