Answer 2

Explanation:

Filtration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid. The term "filtration" applies whether the filter is mechanical, biological, or physical. The fluid that passes through the filter is called the filtrate.

There are basically 4 types of active filters. They are butterworth, Chebyshev, Bessel and Elliptic filters.
