The Fourier transform translates between convolution and multiplication of functions. If f (x) and g (x) are integrable functions with Fourier transforms f̂ (ξ) and ĝ (ξ) respectively, then the Fourier transform of the convolution is given by the product of the Fourier transforms f̂ (ξ) and ĝ (ξ) (under other conventions for the definition of the Fourier transform a constant factor may appear).
