Passive RLC Filter Calculator


Brief for RLC Filter Calculator:

Compute the second order RLC filter using the given formula.

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

Fill the resistance to ccompute the Q factor (quality of circuit), require all other fields filled in.

The resistance is used to compute the Q factor, Higher Q more selective is the filter.
