摘要
This paper analyses the binary expression of ternary signals and the binary construction of circuits, and proposes the design of a mixed-valued counter by using both binary flip-flops and ternary flip-flops ("tri-flops"). Here a new design of an 8421 BCD up-counter based on the mixed-valued binary-binary-ternary-coded decimal (B2TCD) code using mixed-valued logic is presented.
