CALCULATORS
Passive Filter Calculator
A filter is a circuit that is designed to pass signals with desired frequencies and reject or attenuate others. Given the value of the resistor and capacitor, our tool calculates the cut-off frequency of a series RC passive filter.
Low Pass Filter
A Low Pass Filter only allows low frequency signals from 0Hz to its cut-off frequency, ƒc point to pass while blocking those any higher.
