The Sum of minterms and the product of maxterms for the equation is,
F(A,B,C,D) = A'B'C'+BCD
Given:
F(A, B, C, D)
To Find:
The sum of minterms and product of maxterms = ?.
Solution:
According to the problem, expanding the equation,
F(A,B,C,D) = (A'+B)(B'+C)(C'+D)
now, multiply all of it,
= A'(B'+C)+B(B'+C)(C'+D)
= (A'B'+A'C+BB'+BC)(C'+D)
= C'(A'B'+A'C+BB'+BC)+D(A'B'+A'C+BB'+BC)
= A'B'C'+A'CC'+BB'C'+BCC'+A'B'D+A'CD+BB'D+BCD
now, since A', B', and C' are zero, therefore,
F(A,B,C,D) = A'B'C'+BCD
The Sum of minterms and the product of maxterms for the equation is,
F(A,B,C,D) = A'B'C'+BCD
