全加器逻辑符号如图11所示,当Ai=“1”,Bi=“0”,Ci-1=“0”时,Ci和Si分别为()。http://image.zhihuishu.com/zhs/onlineexam/ueditor/201804/69f63296bb78422b9f72c345a9a38ea8.png
举一反三
- 下图器件,当输入变量Ai、Bi、Ci-1的取值分别为1、0、1时,( )。[img=215x266]17da5777ece6f38.png[/img] A: Si=1, Ci=0 B: Si=1, Ci=1 C: Si=0, Ci=1
- 一个全加器,当输入 Ai = 1 、Bi = 0、Ci = 1 时,其和输出Si = ,进位输出Ci+1 =
- 已知:关于Si和Ci+1的逻辑运算式如下: Si = ((Ai XOR Bi) XOR Ci Ci+1 = ((Ai AND Bi) OR ((Ai XOR Bi) AND Ci) ,问: 如果Ai = 1,Bi = 0,Ci = 1,则Si,Ci+1 的值为________。
