Line 26:

=\frac{\mathrm{sinc}(\omega/2)}{\sqrt{2\pi}}</math>

where "sinc" is the [[sinc function (unnormalized)|sinc function]]. Viewing the rectangular function as a [[probability distribution]] function, its [[characteristic function (probability theory)|characteristic function]] is therefore written

:<math>\varphi(k)=\mathrm{sinc}(k/2)\,</math>
