題目二： NAND 是一種邏輯運算子(operator)：a NAND b 定義成 NOT(a AND b)。NOR 也是一種邏輯運算子 (operator)：a NOR b 定義成 NOT(a OR b)。請化簡下列運算式：（以 AND、OR、NOT 邏輯運算子表示）

（三）(a NAND b) NAND (a NAND b) 【4 分】

詳解提供者：林Jacky

Step 1: NOT(NOT(a AND b) AND NOT(a AND b) Step 2: (a AND b) AND (a AND b) Step 3: a AND b

詳解提供者：鴨毛黎俊豪

( NOT(a AND b)) NAND ( NOT(a AND b)) NOT(NOT(a AND b) AND NOT(a AND b)) NOT(NOT(a AND b)) a AND b

(a NAND b) NAND (a NAND b) =NOT(NOT(a AND b) AND NOT(a AND b)) =(a AND b) AND (a AND b) =a AND b

詳解提供者：ycgogo

=NOT(NOT(a AND b) AND NOT(a AND b)) =NOT(NOT(a AND b)) =a AND b

詳解提供者：Ame

(a NAND b) NAND (a NAND b) =(a NOT (a AND b) ) NAND (a NOT (a AND b) ) =(a NOT (a AND b) ) NOT ((a NOT (a AND b) ) AND (a NOT (a AND b) ) )

詳解提供者：Johnny Lin
