What is the Fourier transform of the delta function?
The Fourier transform of a function (for example, a function of time or space) provides a way to analyse the function in terms of its sinusoidal components of different wavelengths. The function itself is a sum of such components. The Dirac delta function is a highly localized function which is zero almost everywhere.What is the Fourier transform of Dirac delta?
So, the Fourier transform of the shifted impulse is a complex exponential. Note that if the impulse is centered at t=0, then the Fourier transform is equal to 1 (i.e. a constant). This is a moment for reflection.- The Fourier transform of the delta distribution is the (distribution corresponding to) the constant function 1 (or possibly some other constant depending on normalization factor - but usually one wants F?=1 such that ? is the identity for convolution).
