Expert Tips
- Always ensure your sampling frequency is at least twice the cutoff frequency.
- Higher filter orders provide better attenuation but increase complexity.
Interactive FAQ
What is the Nyquist frequency?
The Nyquist frequency is half of the sampling frequency.
What is the difference between a low pass and a high pass filter?
A low pass filter allows low frequencies to pass while attenuating high frequencies, while a high pass filter does the opposite.
