- Click the ‘Calculate’ button.
- View the output voltage and chart below.
Formula & Methodology
The formula for calculating the output voltage (Vout) of a low pass filter is:
Vout = (Vin * Rf) / (Ri + Rf)
Where:
- Vin is the input voltage
- Ri is the input resistance
- Rf is the filter resistance

| 5 | 3.33 |
| 10 | 6.67 |
| 15 | 9.99 |
Expert Tips
- Always ensure the input resistance is much higher than the filter resistance for accurate results.
- Consider using a logarithmic scale for the chart to better visualize small differences in output voltage.
Interactive FAQ
What is the difference between a low pass filter and a high pass filter?
A low pass filter allows low-frequency signals to pass while attenuating high-frequency signals. A high pass filter does the opposite.
