RC High Pass Filter Calculator

High Pass Filter Calculator, Theory, and Simulations with KiCad RC Low Pass Filter

High Pass Filter Calculator, Theory, and Simulations with KiCad RC High Pass Filter


Low Pass Calculator

Set the resistance scale, capacitance scale, and optional input voltage then the RC filter calculator will plot the low pass graph. If input voltage is blank the graph defaults to percentage for the linear scale

Vin (optional)
-3 Db point: 93.621 Hz

High Pass Calculator

Set the resistance scale, capacitance scale, and optional input voltage then the RC filter calculator will plot the high pass graph. If input voltage is blank the graph defaults to percentage for the linear scale
