Calculate Cutoff Frequency



Formula

The formula to calculate the Cutoff Frequency (f) is:

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

What is Cutoff Frequency?

A cutoff frequency is defined as the frequency at which an electrical system starts to reduce the amount of energy it lets through.

Example Calculations

Example 1:

Using the formula:

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

Example 2:

Using the formula:

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