Tried to add some precision to the article, still needs a lot of work to get it in shape. For example, it doesn't really make sense to talk about orthogonality of a family of sine and cosine functions ranging over a continuum of frequencies from $\scriptstyle -\infty$ to $\scriptstyle \infty$ , in what sense are they orthogonal? This is different from the case of a Fourier series in which you have a family sine and cosine functions whose frequencies are integral multiples of some fundamental frequency. Hendra I.

I would extend the article with content from http://tori.ils.uec.ac.jp/TORI/index.php/Fourier_transform Any objections? Dmitrii Kouznetsov 11:16, 2 September 2012 (UTC)
