Equal Component Butterworth High Pass Filter
Calculator 



Enter value of Cutoff Frequency, any one value  Resistor or Capacitor,
any one value  Resistor R_{c} or Resistor R_{d} and click on calculate. Result will be displayed.

R_{a} = Filter Resistor R_{b} = Filter Resistor
(R_{a} = R_{b}) C_{a} = Filter Capacitor
C_{b} = Filter Capacitor (C_{a} = C_{b})
R_{c} = Feedback Resistor R_{d} = Feedback Resistor
