Question

EXAMPLE 19
Design a logic circuit and draw its
diagram for the Boolean expression:
(A+B)(C+ D)C.
SOLUTION​

Answer 1

Answer:

It can be simplified as

(BC+A)(A′ B ′+C ′ )+A ′B ′ C ′

B C A ′ B ′ +BCC ′ +AA ′ B ′ +AC ′ +

A ′ B ′ C ′

A ′ C B B ′+BCC ′ +AA ′ B ′ +AC ′ +

A ′ B ′ C ′

0+0+0+AC ′ +A ′ B ′ C '

=C ′ (A+A ′ B ′)

=[(A+A ' )(A+B x′ )]C ′

=(A+B ′ )C ′
