12–48 A series RLC bandpass filter is required to have resonance at f0 = 50 kHz. The circuit is driven by a sinusoidal source with a Thévenin resistance of 60 Ω. The following standard capacitors are available in the stock room:

1 μF, 0:68 μF, 0:47 μF, 0:33 μF, 0:2 μF, and 0:12 μF. The inductor will be custom-designed to match the capacitor used.

Select the available capacitor that minimizes the filter bandwidth.
