Web9.2.1.4 Higher-Order Low-Pass Filters. High-order filters are used because they have the ability to roll off gain after the bandwidth at a sharper rate than low-order filters. The attenuation of a filter above the bandwidth grows proportionally to the number of poles. When rapid attenuation is required, higher-order filters are often employed.
