This formula uses 1 Constants, 3 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Cut-off Frequency - (Measured in Hertz) - A Cut-off Frequency is a boundary in a system's frequency response at which energy flowing through the system begins to be reduced rather than passing through.
Capacitance - (Measured in Farad) - Capacitance is the capability of a material object or device to store electric charge. It is measured by the change in charge in response to a difference in electric potential.
Resistance - (Measured in Ohm) - Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
STEP 1: Convert Input(s) to Base Unit
