- Enter the desired cutoff frequency (Fc).
- Click ‘Calculate’.
Formula & Methodology
The formula for calculating the low pass filter cutoff frequency is…
Real-World Examples
Example 1
In a audio processing system with a sampling frequency of 44.1 kHz…
Data & Statistics
| Sampling Frequency (Fs) | Cutoff Frequency (Fc) | Result |
|---|---|---|
| 44.1 kHz | 20 kHz | 0.452 |
| 48 kHz | 24 kHz | 0.5 |
Expert Tips
- Always ensure the cutoff frequency is less than half the sampling frequency.
- Consider the trade-off between filter order and transition bandwidth.
Interactive FAQ
What happens if Fc is greater than Fs/2?
Aliasing occurs, leading to distortion and loss of information.
