Easily determine the cutoff frequency (fc) for your RC (Resistor-Capacitor) low-pass and high-pass filters with our free online calculator. Input your resistance and capacitance values to quickly find the critical frequency where the signal power is halved. Perfect for electronics students, hobbyists, and professional engineers designing passive filters.
Formula:
The cutoff frequency (fc) for an RC filter is given by the formula:
fc = 1 / (2πRC)
Where:
fc = Cutoff Frequency (in Hertz)
R = Resistance (in Ohms)
C = Capacitance (in Farads)
