Realize each of these POS expressions with its equivalent logic gate circuit:

(A+B)(A+B’)

(A+B+C)(A’+B+C’)(A+B+C’)

Realize each of these SOP expressions with its equivalent logic gate circuit:

AB+A’B’

ABC+A’BC’+ABC’

Simplify the following expression to obtain SOP and Realize with logic gate circuit:

(A + B) (A + C’) (B’ + C’)

AB + (AC)’ + AB’C (AB + C)
