The Q of a tuned circuit refers to the property of_______________?
Correct answer: C. Selectivity
- A. Sensitivity
- B. Fidelity
- C. Selectivity
- D. None of the above
Explanation
The Q-factor of a tuned circuit indicates how sharply it responds around resonance. A high Q gives a narrow bandwidth and therefore better selectivity, not necessarily better fidelity or sensitivity.
