{wiki=Favard's_theorem}
Favard's theorem is a result in functional analysis and measure theory concerning the Fourier transforms of functions in certain spaces. Specifically, it deals with the conditions under which the Fourier transform of a function in \\( L^1 \\) space can be represented as a limit of averages of the values of the function.
