The Fourier integrals are treated as a rigorous extension of the Fourier series expansion. The reward for this is that so called, in the Fourier integrals, singular functions that are not absolutely integrable, e.g., trigonometric functions can be discussed within a field of ordinary function giving a foundation for the delta function as distribution.
