The complement of the function F = (A + B’)(C’ + D)(B’ + C) is:
(A) A’B + CD’ + BC’
(B) AB’ + C’D + B’C
(C) AB’ + CD’ + BC
(D) AB + BC + CD
Answer: (A)
Explanation: Using Demorgan’s Law (Break the line, change the sign)
Complement of
F = F’ = ((A + B’)(C’ + D)(B’ + C))’
F’ = ((A + B’))’ + ((C’ + D))’ + ((B’ + C))’
F’ = A’B + CD’ + BC’
