WebSorted by: 35. Let f, g be functions of a real variable and let F ( f) and F ( g) be their fourier transforms. Then the fourier transform is linear in the sense that, for complex numbers a and b, F ( a f + b g) = a F ( f) + b F ( g) i.e. it has the same notion of linearity that you may be used to from linear algebra.
