Hi All,
Usually the Fourier transform is defined as the one in the Wiki page here (http://en.wikipedia.org/wiki/Fourier_transform), see the definition.
My question is can I define Fourier transform as [itex]\int[/itex]f(x)e[itex]^{2\pi ix \varsigma}[/itex]dx instead, i.e., with the minus sign removed, as the forward Fourier transform? The backward one is the one with the minus sign. So the definition is the opposite to the definition on the wiki page.
Can I define this? Will the so-transformed frequency domain still bear the physical meanings as we usually talk about?
Thanks in advance. Any comment will help.
Jo
