| 3 | 100 | 0.46 |
Expert Tips
- Always consider the trade-off between filter order and phase shift.
- Use a higher order filter for a sharper cutoff.
Interactive FAQ
What is the difference between a low pass and a high pass filter?
A low pass filter allows low frequencies to pass and attenuates high frequencies, while a high pass filter does the opposite.
NASA’s Jet Propellant Test Facility is an example of a low pass filter in action.
University of Edinburgh’s Acoustics Research provides more information on acoustic filters.
