of class.
1.
Complete the following exercise for the expression
F = (A’+B’+C’) (A’+B’+C) (A’+B+C’) (A’+B+C) (A+B+C)
a.
Write the PoS expression using Pi Notation
b.
Write the equivalent SoP expression in Sigma Notation.
c.
Write the SoP expression as an expanded logic expression, i.e., write F =
f
(A,B,C)
d.
Reduce the expression from (c) using KMap.
e.
Reduce the expression from (c) using Boolean algebra, but keep your answer is a SoP
form, i.e. using only terms containing ANDs that are ORed together. Does this agree
with part (d)? If not, look for mistakes.
f.
Can your expression from (d) and (e) be minimized further to reduce the number of
terms and/or operations? If so, write the minimized expressions.
g.
Draw the gatelevel schematic for the minimized expression using any appropriate
basic logic gate. Use only A , B , C as inputs –no complements.
