Interactive FAQ
What is the difference between a low pass and a high pass filter?
A low pass filter allows signals below a certain frequency to pass, while a high pass filter allows signals above a certain frequency to pass.
How do I choose the right capacitor value?
Start with a value that’s close to the desired cutoff frequency, then adjust based on the results.
