帮忙看下数字电路的题,
1）How many
gates (only AND and OR gates are available) are required to implement the
following functions TOGETHER (Uncomplemented inputs are available)?F = a'c' +
ab,G = a'c + ab
“Uncomplemented inputs are available”是什么意思?我觉得uncomplemented是补码的反义词,那意思就是abc可以作为输入端?这不是废话吗?
2）如果函数是 F = ab +
cd,G = ab + c'd + e呢?就需要六个门吧?
答
Uncomplemented inputs are available只有原变量输入 没有现成的反变量输入；其余答不了
