Filters transform data.
Filters sorts or makes order of pattern.
Filters transform images in an unusual way.
Filters manipulate data.
In Telle-communication filters selectively sort signals
Filters are used to surpress noise or they separate signals
Filters give a particular effect used to apply to image.
Gelatin filters are used over the lens of a camera to absorb specific wavelengths of light.
