In a series resonant band-pass filter, a lower value of Q results in

[A]. a higher resonant frequency
[B]. a smaller bandwidth
[C]. a higher impedance
[D]. a larger bandwidth

Answer: Option D

Because bandwidth is (f2-f1) is inversly proportional to Q i.e. quality factor.

(f2-f1) /f0 = 1/q0.

Bandwidth = fr/q if q is lower value obviously the bandwidth is larger.

Bandwidth = fr/q.

If q is lower value obviously the bandwidth is larger.

1/R √L/C = Fr/BW increasing bandwidth quality factor is refused.

Band width and quality factor both are inverse together, so one is high and another is low.
