Question

Create the equivalent logic circuit of the following logic expression:

1. Q = (A + B) . (C +D)'

2. F1 = (A + BC') . D

3. Q = [(A + B)' . C] +B . C 

Answer 1

1)Given logic expression is

$Q = (A + B) . (C +D)'\\=(A+B).(C'.D')$

2)Given logic expression is

$F_1 = (A + BC') . D$

3)Given logic expression is

$Q = [(A + B)' . C] +B . C\\=[A'.B'.C]+B.C$
