In contrast to such a solution, in this paper, a sharpening filter
is implemented with FIR filters
[1,3,18,19], the classical Gaussian filter
has many excellent properties, such as zero-phase characteristic, minimum product of time width and frequency width, isotropic characteristic, and perfect separability of the 3D Gaussian function into filters
operating in the x- and y-directions.
A furnace filter
removes dust, dander and other large particulates from the air in our homes when either the furnace or central air conditioner is running, as the two systems share common ductwork for air distribution.
