摘要
8-3编码器是一种普通二进制编码器,对应的是八个变量的卡诺图,其最小项的排列及化简较复杂.用格雷码排列了卡诺图的最小项,通过几何位置确定了最小项的逻辑相邻项,然后用卡诺图化简法使这些逻辑相邻项得到了化简,并得出了8-3编码器的逻辑表达式.
8-3 encoder is an ordinary binary encoder and corresponding to the Karnaugh map of eight variables, whose arrangement of the smallest item and simplify is complex. This paper used the gray code to arrange the smallest items, and according to geometrical position determined the logic adjacent items. Then used the karnaugh map reduction method to Simplify the smaUest item and got the logical expression of the 8-3 encoder.
