Brickwall Filter

Some low pass filters are designed with such a steep cutoff slope that they resemble a “brick wall.” These types of filters have often been used as anti-aliasing (see WFTD archive Aliasing) filters for A/D converters (see WFTD archive A/D Converter). Designers prefer not to use them because their severe nature often has negative side effects on the unfiltered audio such as phase shift and non linearity near the cutoff point.
