brickwall filter

A brick wall is a wall of bricks. The term brickwall filter stands for a low-pass filter with a steep cutoff frequency.

Brickwall filters are often used in A/D converters and prevent aliasing. Since the cutoff frequency has a steep slope, undesirable side effects can occur in audio technology and negatively affect the audio signal. For example, phase shifts.
