Question:-
Option (A)
Both A and Rare true and R is the correct explanation of A.
Option (B)
Both A and R are true but R is NOT the correct explanation of A
Option (C)
A is true but R is false
Option (D)
A is false but R is true
Correct Option:
B
Question:-
Option (A)
Both A and Rare true and R is the correct explanation of A.
Option (B)
Both A and R are true but R is NOT the correct explanation of A
Option (C)
A is true but R is false
Option (D)
A is false but R is true
Correct Option:
D
Question Solution:
(FFH)16 = (255)10
(80H)16 = (128)10
Input for the output of 80H is
- 5 + (128 / 255) x [5 –(-5)], i.e. 0V.
Question:-
Option (A)
(A + B).(`A +C).(B+C)=(A+B).(`A +C)
Option (B)
AB + `AC + BC = AB + BC
Option (C)
AB+ `AC + BC = (A+B).(`A +C).(B+C)
Option (D)
(A+B).(`A +C).(B+C)=AB+ `A C
Correct Option:
A
Question Solution:
AB + `AC + BC = AB + `AC
Changing the binary operators,
(A + B) (`A + C) (B + C) = (A + B) (`A + C)
Question:-
Option (A)
Option (B)
Option (C)
Option (D)
Correct Option:
D
Question Solution:
Question:-
Option (A)
1
Option (B)
zero
Option (C)
X
Option (D)
`X
Correct Option:
B
Question Solution:
Y = X Å [ X Å { X Å X}]
Þ Y = X Å [X Å 0]
Þ Y = X Å X
Þ Y = 0
