Question:
Consider the following minterm expression for \( F \): \[ F(P, Q, R, S) = \Sigma(0, 2, 5, 7, 8, 10, 13, 15) \] \(\text{The minterms 2, 7, 8, and 13 are don't care terms. The minimal sum of products form for F is}\)
Consider the following minterm expression for \( F \): \[ F(P, Q, R, S) = \Sigma(0, 2, 5, 7, 8, 10, 13, 15) \] \(\text{The minterms 2, 7, 8, and 13 are don't care terms. The minimal sum of products form for F is}\)
Show Hint
When simplifying Boolean expressions with don't care terms, group the terms strategically to minimize the number of product terms.

- \( \overline{Q}S + QS \)
- \( \overline{Q}S + QS \)
- \( \overline{Q}RS + Q\overline{R}S + QR\overline{S} + QRS \)
- \( \overline{P}QS + PQS + PQ\overline{S} + P\overline{Q}S \)

The Correct Option is B
Solution and Explanation
To minimize the given minterms, we use the don't care terms (2, 7, 8, and 13) to simplify the Boolean expression. By grouping the terms appropriately, we can reduce the expression to:
\[ \overline{Q}S + QS \] This is the minimal sum of products form for \( F \). Thus, the correct answer is \( \boxed{\overline{Q}S + QS} \).
\[ \overline{Q}S + QS \] This is the minimal sum of products form for \( F \). Thus, the correct answer is \( \boxed{\overline{Q}S + QS} \).
