LC Low Pass Filter Online Calculator
Introduction & Importance
An LC low pass filter is an electronic filter that allows low-frequency signals to pass while attenuating (reducing the amplitude of) signals with frequencies higher than the cutoff frequency. This is achieved using an inductor (L) and a capacitor (C) in series, with the output taken between them.
LC filters are essential in various applications, including audio processing, signal conditioning, and power electronics.
What is the cutoff frequency of an LC low pass filter?
The cutoff frequency (fc) of an LC low pass filter is given by the formula fc = 1 / (2π√(LC)).
