The domain of the expression AB'CD+AB'+C'D+B is A,B,C and D
举一反三
- The domain of the expression AB'CD+AB'+C'D+B is表达式AB'CD+AB'+C'D+B的域是 A: A and DA和D B: B only只有B C: A ,B,C, and DA、B、C和D D: none of these这些都不对
- 将逻辑函数Y=AB'D'+B'C'D+A'D+AB'C+A'B'CD'化为最简与或函数为()。 A: AB'+A'D+B'C+AD' B: AB'+A'D C: AB'+A'D+B'C D: AB'+A'D+B'D
- Simplify the expression X=AB(CD'+EF) , we may get
- 设A,B,C,D为四个相异的共线点,则(AB,CD)=-1的充要条件是 A: (AB,CD)=(AC,DB) B: (AB,CD)=(AC,BD) C: (AB,CD)=(DC,AB) D: (AB,CD)=(DC,BA)
- 已知逻辑函数的真值下表所示,的逻辑函数式为。() A: A’B’C’D+A’B’CD’+A’BC’D’+A’BCD+AB’C’D’+AB’CD+ABC’D+ABCD’ B: A’B’C’D’+A’B’CD’+A’BC’D’+A’BCD+AB’C’D’+AB’CD+ABC’D+ABCD’ C: A’B’D’+A’B’C+B’CD+A’CD+AB’C’D’ +ABC’D+ABCD’ D: A’B’D+A’B’C+B’CD+A’CD+AB’C’D’ +ABC’D+ABCD’
