Calculate Cutoff Frequency



Formula

To calculate the cutoff frequency of a high pass filter:

\[ f_c = \frac{1}{2 \pi R C} \]

What is a High Pass Filter?

A high pass filter is defined as a circuit or electrical system that only passes signals above a certain cutoff frequency. Any signal greater than the cut-off will be passed. It is used to remove low-frequency components from a signal, allowing high-frequency components to pass through.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ f_c = \frac{1}{2 \pi \times 1000 \times 0.000001} = 159.15 \text{ Hz} \]

The cutoff frequency is 159.15 Hz.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ f_c = \frac{1}{2 \pi \times 500 \times 0.000002} = 159.15 \text{ Hz} \]

The cutoff frequency is 159.15 Hz.
