For an experiment about Holograms I have to find a couple of Fourier transformations. The one I'm having troubles with is the following:(adsbygoogle = window.adsbygoogle || []).push({});

Find the Fouriertransform of a rectangular wave:

thus: f(x)=1 from (-5b,-3b), (-b,b) and (3b,5b) and (7b,9b) etc.

and f(x) = -1 from (-3b,-b), (b,3b), (5b,7b) etc.

Could someone give me a hint?
