Product-of-Sums (POS) Form

PRODUCT-OF-SUMS (POS) FORM:

•               Two or more sum terms multiplied by Boolean multiplication

•               Any expression -> POS using Boolean algebra

•               Examples:

(A+B)(B+C)(A+B+C)

1. PRODUCT-OF-SUMS (POS) FORM:

•               Conversion to POS Form:

*              AB+ B(C + D) = B(A + C + D)

*              AB+ ACD = A(B + CD) = A(B + C)(B + D)

2. IMPLEMENTATION OF POS EXPRESSION:

(A+B)(B+C+D)(A+C)
