Equal Component Butterworth Low Pass Filter Calculator

Enter value of Cutoff Frequency, any one value - Resistor or Capacitor, any one value - Resistor Rc or Resistor Rd and click on calculate. Result will be displayed.

Ra = Filter Resistor
Rb = Filter Resistor
(Ra = Rb)
Ca = Filter Capacitor
Cb = Filter Capacitor
(Ca = Cb)
Rc = Feedback Resistor
Rd = Feedback Resistor
