Passive Band-Pass Filter Calculator

This is a first-order, single pole, passive RC band pass filter calculator composed of two RC filters, a high pass followed by a low pass. Set the desired cutoff frequency to generate resistor and capacitor values, then adjust the bode plot max frequency to view the response over the desired frequency sweep.
