| Abstract: | The matrix transform method between the maxterm expansion and COD expansion for logical function were discussed and the graphic method of the conversion from K map to gj map was analyzed.Based upon it , a tabular method between the maxterm expansion coefficients and the division-coincidence expansion coefficients was presented.In comparison with the graphic method, this tabular method has several advantages such as without the restriction of the number of variables, and to be suited to programming on computers, which is quite practicable. |
