| 1000 | -3 |
| 2000 | -12 |
Expert Tips
- Always use a Q value that suits your specific application.
- Consider the trade-off between filter order and Q.
Interactive FAQ
What is the difference between a low pass and high pass filter?
A low pass filter allows low frequencies to pass and attenuates high frequencies, while a high pass filter does the opposite.
