A certain band-pass filter has a center frequency of 15 kHz and a bandwidth of 1 kHz. Determine the Q and classify the filter as narrow-band or wide band.
Q=\frac{f_0}{B W}=\frac{15~ \mathrm{kHz}}{1 ~\mathrm{kHz}}=15
Because Q > 10, this is a narrow-band filter.

If the Q of the filter is doubled, what will the bandwidth be?
