A parallel resonant band-pass filter consists of a 90 Ω resistor in series with a parallel network made up of a 60 mH coil and a 0.02 µF capacitor. The output is taken across the capacitor/coil. The coil winding has a resistance of 20 Ω. What is the center frequency of the filter?
(A) 459 Hz
(B) 4,591 Hz
(C) 999 Hz
(D) 2,176 Hz
