Solution:
b.
F = xy’z + x’ y’ z + w’ xy + wy + wx’ y + wxy
a)
c) F = xy’ z + x’ y’ z + w’ xy + wx’ y + wxy
= (x +x’) y’ z + y (w’ x + w(x + x’)
a + a’ = 1 => F = y’ z + y(w’ x + w)
a + a’ b = a + b => F = y’ z + y(w + x).
d) Wxyz F
Both are same
e) For simplified expression clearly itrequires only a not gate, two 2-input AND gates and two 2-input ORgates
