The formula to calculate the cutoff frequency of an RL low-pass filter is:
\[ f_c = \frac{R}{2\pi L} \]
Where:
An RL low-pass filter is an electronic circuit consisting of a resistor (R) and an inductor (L) connected in series. It allows low-frequency signals to pass through while attenuating high-frequency signals. The cutoff frequency is the frequency at which the output voltage is reduced to 70.7% of the input voltage.
Let's assume the following values:
Step 1: Calculate the cutoff frequency:
\[ f_c = \frac{5.6 \times 10^3}{2\pi \times 250 \times 10^{-3}} \approx 3.57 \, kHz \]
