Fourier transform same as signal.

  1. Nov 25, 2009 #1
    Hi friends,

    I was looking for signals which will have themselves as the Fourier transform. Few of them are given below.

    \frac{1}{\sqrt{2\pi}}e^{-\frac{t^2}{2}}\longrightarrow e^{-\frac{\omega^2}{2}}

    \sum_{k=-\infty}^{\infty}\delta(t-kT)\longrightarrow \frac{2\pi}{T}\sum_{n=-\infty}^{\infty}\delta(\omega-\frac{2\pi n}{T})

    can you suggest any other signals which satisfy the property?

    A pulse in the shape of a gaussian curve?

    That is what I have given as the first example.
