Filter cutoff frequency online calculator

The RC filter, also known as the RC circuit, is a circuit that includes a voltage source, a current source to drive the resistor, and a capacitor.

On this page, the RC filter calculator can calculate the cutoff frequency of high-pass and low-pass filters online. The calculation tools are as follows:

The RC filter has been developed to calculate the cutoff frequency of its single order at a rate of 6dB. Try out Low Pass High Pass (Hih Pass) filtering.
