Digital circuits and logic rules: do digital circuits obey Boolean logic? Evaluate the claim: “A digital circuit will not obey a set of logic rules.” In the context of Boolean algebra, logic families, and truth tables, determine whether the statement is valid.

Introduction / Context:
Digital electronics is grounded in Boolean algebra. Gates, flip-flops, and combinational/sequential circuits are designed to implement precise logical relationships. This item checks conceptual clarity about whether digital circuits are expected to follow defined logic rules.

Given Data / Assumptions:

• Ideal operation assumes valid input levels within specified thresholds.
• Timing requirements (setup, hold, propagation) are met.
• Supply rails, temperature, and loading remain within data sheet limits.

Concept / Approach:
Truth tables and Boolean expressions define how outputs should respond to inputs. Within specified operating conditions, gate-level hardware reliably enforces these rules. Deviations arise only when constraints are violated (e.g., undefined inputs, excessive fanout, noise, or timing violations), which does not negate the existence of the rules—only the validity of the operating point.

Step-by-Step Solution:

Verification / Alternative check:
Simulate a circuit in a HDL or measure with a logic analyzer; outputs match truth tables when operated within specs.

Why Other Options Are Wrong:

Common Pitfalls:
Mistaking symptoms of bad design (glitches from timing violations, improper termination) as evidence that logic rules are invalid.

Final Answer:
Incorrect
