Passive RC Filter Calculator


Brief for RC Filter Calculator:

Compute the first order RC filter using the given formula.

Fill two of the three fields to compute de desired value, the frequency, the resistance or the capacitance.


Brief for RC Filter circuit:

Below are the arragement for acting as high-pass or low-pass frequency. Just the arrangement indicates it's an high-pass or low-pass.
