Guitar Pedals: R-C Filter Calculator

  • Simple R-C Filter Cutoff








    The simple R-C filter rolls off the frequency response at 6 dB per octave above the cutoff frequency. The position of the resistor and capacitor are switched to change from low pass to high pass but the same calculation applies to both filters. This calculator assumes a low source impedance, which usually is small enough that it does not change the corner frequency.
