A Fourier-like transform suitable for application to digital functions is considered, and the difference operators for these functions are discussed. Special attention is focused to the relationship between the Fourier transform of a function and the Fourier transform of its difference relative to a particular variable. Using the transform introduced, a polynomial expansion for digital functions is suggested
