A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. A low-pass filter is the complement of a high-pass filter. In optics, high-pass and low-pass may have different meanings, depending on whether referrin… WebA low pass filter allows signals lower than a cut-off frequency to pass, whereas a high pass filter allows signals higher than a cut-off frequency to pass. The frequency of the cutoff is …
