Abstract: Based on the Binary-Coded Trinary（BCT） encoding algorithm，some trinary data encoding methods are discussed.A “module-combination” design method is proposed and used in the design and realization of the trinary data encoding circuit using division-by-three modules.The method has several advantages over the other proposed methods，especially in that it is flexible and adaptive to design corresponding three-state encoding circuit for different model（N，M） presented in the paper.As an illustrative example，a （4，2） model trinary encoding circuit is constructed.
