The cut-off frequency of a low pass filter represents the frequency at which the filter starts to attenuate the signal. Below the cut-off frequency, the filter allows the signal to pass through with minimal attenuation. As the frequency increases beyond the cut-off point, the filter attenuates the signal to a greater extent. The roll-off rate of the filter, which determines the sharpness of the transition from passband to stopband, is also an important characteristic.
