If Q of an LC circuit increases, then bandwidth ______________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remains the same
- D. Insufficient data
Explanation
For a resonant circuit, Q = f₀/BW, so bandwidth is inversely proportional to quality factor when the resonant frequency is fixed. Therefore, increasing Q decreases the bandwidth.
