Passive LC Filter Calculator


Brief for LC Filter Calculator:

Compute the second order LC filter using the given formula.

Fill two of the three fields to compute de desired value, the frequency, the capcitance or the indutance.


Brief for LC Filter circuit:

Below are the arragement of the LC Filter circuit to act as high-pass or low-pass frequency. Just the arrangement indicate it's an high-pass or low-pass.
