I'm rather sure that the scaling part is wrong -- tri(t/a) = conv(rect(t/a),rect(t/a)). Plug that into convolution formula and you get something different than what is shown in the "scaling" section of the main page. Draw the convolution on paper if you need convincing. The convolution of rect(t) and rect(t/a) will not become non-zero at -a. Instead, it will become non zero at something like (-a - 1)/2. Andrew.kintz (talk) 23:49, 7 November 2009 (UTC)

Article could be more clear about the notation for a triangle function of height other than 1, so that one could understand the tables given in the continuous fourier transform article.Dsolderthis (talk) 05:45, 23 April 2008 (UTC)
