GATE EE 2004 | Boolean Algebra Question 8 | Digital Electronics

GATE EE 2004

MCQ (Single Correct Answer)

-0.6

The simplified form of the Boolean expression $$Y = \left( {\overline A BC + D} \right)\left( {\overline A D + \overline B \overline C } \right)$$ can be written as

$$\overline A D + \overline B \overline C D$$

$$AD + B\overline C D$$

$$\left( {\overline A + D} \right)\left( {\overline B C + \overline D } \right)$$

$$A\overline D + BC\overline D $$

GATE EE 2003

MCQ (Single Correct Answer)

-0.6

The Boolean expression $$X\overline Y Z + XYZ + \overline X Y\overline Z + \overline X \overline Y Z + XY\overline Z $$ can be simplified to

$$X\overline Z + \overline X Z + YZ$$

$$XZ + \overline Y Z + Y\overline Z $$

$$\overline X Z + YZ + XZ$$

$$\overline X \overline Y + Y\overline Z + \overline X Z$$
