| Abstract: | When variable quantity lacks,Karnamgh map simplification is used,but it applies to grade 2 circuit design.To make a stude of simplification of Karnaugh map algorithm in grade 3 NAND circuit design and solve the problem of functional expression in designing:Reducimg the numbers of the 2nd grade NAND gate utilizing the combination of product phrases;Reducing the numbers of the lst grade NAND gate utilizing tail factor,the result shows that the method is direct and simplification is rapid.It expands the Karnamgh map algorithm. |
| Keywords: | Karnamgh-map grade 3 circuit NAND gate |
