High Pass Filter Calculator

Enter the resistance and capacitance of a high pass filter into the calculator to determine the cut-off frequency of the filter.

High Pass Filter Formula

The following formula is used to calculate the cutoff frequency of a high pass filter.

fc = 1 / (2*pi*R*C)

  • Where fc is the cutoff frequency (hz)
  • R is the resistance
  • C is the capacitance

High Pass Filter Definition

A high pass filter is defined as a circuit or electrical system that only passes signals above a certain cutoff frequency. That is any signal greater than the cut-off will be passed.

High Pass Filter Example

How to calculate cut-off frequency of a high pass filter?

  1. First, determine the resistance.

    Calculate or measure the total resistance of the filter.

  2. Next, determine the capacitance.

    Calculate of measure the total capacitance of the filter.

  3. Finally, calculate the high pass filter.

    Calculate the frequency of cut-off of the high pass filter using the equation above.
