Cutoff Frequency Calculator

Enter the resistance and capacitance of a simple first order low pass filter into the calculator to determine the cutoff frequency.

Cutoff Frequency Formula

The following formula can be used to calculate a cutoff frequency.

f = 1/ 2 * pi * R * C

  • Where f is the cutoff frequency (hz)
  • R is the resistance (ohms)
  • C is the capacitance (farads)

FAQ

What is a cutoff frequency?

A cutoff frequency is a certain frequency in which the system starts to reduce the amount of energy it lets pass through begins to be reduced.


Example

How to calculate cutoff frequency?

  1. First, determine the resistance.

    Measure the resistance in ohms of the low pass filter system.

  2. Next, determine the capacitance.

    Of the same system, measure the capacitance in microfarads.

  3. Finally, determine the cutoff frequency.

    Calculate the cutoff frequency using the formula above.
