Difficulty: Easy
Correct Answer: Correct
Explanation:
Introduction: Simplifying logic reduces gate count, wiring, and power while preserving function. Boolean algebra provides a rigorous rule set for performing such reductions by hand, complemented by methods like Karnaugh maps and Quine McCluskey.Given Data / Assumptions:
Concept / Approach: Boolean algebra identities (idempotent, null, identity, complement, absorption, De Morgan, etc.) enable stepwise elimination of redundant literals and terms. These transformations map to fewer or simpler gates when implemented.Step-by-Step Solution:
Step 1: Write the expression in SOP or POS form.Step 2: Apply identities to merge terms and drop redundancies.Step 3: Optionally validate with Karnaugh maps or truth tables.Verification / Alternative check:
Compare outputs for all input combinations before and after reduction; they match, confirming equivalence.Why Other Options Are Wrong:
Incorrect: Conflicts with standard practice across textbooks and tools.Only possible with Karnaugh maps: K-maps are one method; Boolean algebra works directly as well.Only possible with computer synthesis: Manual algebraic reduction predates automated tools.Common Pitfalls:
Stopping early and leaving near-redundant terms.Mixing arithmetic intuition with Boolean rules.Final Answer:
Correct
