| Abstract: | The design method of multivalued shift-register type counter based on all state map is analyzed and discussed, and then it is pointed out that the number of states for multivalued multi-variable shift-register type counters will increase rapidly with the increment of the radix of the multivaued logic, which makes the multivalued all state very complicated, thus leading to the loss of the features such as intuition and convenience. To overcome this disadvantage the multivalued all state table is presented and a practical example of two-variable quaternary shift-register type counter is given. |

| Keywords: | multivalued logic shift register counter all state maps all state tables |
