The linearity property of a transform T{} is verified if

a f(x) + b g(x) -T-> a T{f(x)} + b T{g(x)}

where a and b are constants, f(x) and g(x) are functions and -T-> denotes the transformation.

A transform is thus linear if any linear combination of functions are transformed into a linear combination of their transforms.
