The formula to calculate the Cutoff Frequency (f) is:
\[ f = \frac{1}{2 \pi R C} \]
Where:
A cutoff frequency is defined as the frequency at which an electrical system starts to reduce the amount of energy it lets through.
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:
\[ f = \frac{1}{2 \pi \times 500 \times 0.000002} \approx 159.15 \text{ Hz} \]
