| Abstract: | Based on the discussion of CRM expansion,the classification of logical functions and the P classification table of three-variable functions,input permutation table and input connection table of representative functions of P classification are provided.Based on three-variable universal-threshold-logic gates with complementary outputs,a tabular design method to an arbitrary logic function expressed in CRM expansion is proposed.It is proved by several design examples that the method has many advantages,such as simplicity,intuition and so on. |
