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.
