| Feb 22, 2012 at 18:30 | comment | added | Dilip Sarwate | See the answers to a related recent question on math.SE which will also tell you how to use tables of common Fourier transform pairs with respect to the radian frequency variable $\omega$ radians/second to obtain Fourier transform pairs with respect to frequency variable $f$ in Hertz. For the particular case of impulses in time or frequency, the key is the sifting property: $$\int_{-\infty}^{\infty} x(y) \delta(y-a)\mathrm dy = x(a) ~ \text{if}~x(y)~\text{is continuous at}~a.$$ | |
