In a series resonant band-pass filter, a lower value of Q results in______________?
Correct answer: D. a larger bandwidth
- A. a higher impedance
- B. a smaller bandwidth
- C. a higher resonant frequency
- D. a larger bandwidth
Explanation
For a resonant filter, Q = fr/BW, so bandwidth is inversely proportional to Q. A lower Q therefore produces a larger bandwidth and poorer selectivity.
