Band-pass filter
= Band-pass filter
{wiki}
A band-pass filter preferentially transmits signals within a range of <frequencies> and attenuates sufficiently lower and higher <frequencies>. Taking the output voltage across the <resistor> in a <series RLC circuit> gives one example: the <resonant series RLC response> selects a band around $1/\sqrt{LC}$. https://www.feynmanlectures.caltech.edu/II_22.html#Ch22-S7[Feynman lectures, II.22.7: resonant frequency filters]{ref}.
