Ans SOP Form is : X‟.Y‟.Z + X‟.Y.Z‟ + X.Y.Z‟ + X.Y.Z

(1 mark for correct answer)
Note: Deduct ½ mark if wrong variable names are written in the expression
(d) Reduce the following Boolean expression using K-Map:- 3
F(U,V,W,Z)= π(0,2,5,7,12,13,15)

Ans POS form using K-Map is given as:-

Quad 1: (V‟+Z')
Pair 1: (U+V+Z)

Pair 2: (U‟+V‟+W)
POS Form: (V‟+Z').(U+V+Z).(U‟+V‟+W)

( ½ Mark for drawing K‐Map with correct variable names)
( ½ Mark each for correct placement of 0)
( ½ Mark each for 3 groupings)
( ½ Mark for writing final expression in reduced/minimal form)
Note: Deduct ½ mark if wrong variable names are used
