The Fourier transform: The Fourier transform can be viewed as an extension of the above Fourier series to nonperiodic functions. For completeness and for clarity, I'll define the Fourier transform here. If x ( t) is a continuous, integrable signal, then its Fourier transform, X ( f) is given by. X ( f) = ∫ R x ( t) e − ȷ 2 π f t d t, ∀ ...
