An electric filter is often a frequency selective circuit that passes a specified band of frequencies and block or attenuates signals of frequencies outside this band.. If the quantity we are trying to measure is continually changing, will we be able to follow it? If the changes speed up, at what point will we fail to keep up with the changes? This is the . cut-off frequency.
