How is the fourier transform applied to

**non-periodic**functions, such as the Rect function?

Any help would be

**greatly**appreciated,

Cheers,

Jamie :)

What i mean is, say, how would you show that the FT transform of {1} is a delta function??

The transform you specified will lead you to integrate exp( - i * w * t ) with t ranging from -A to A, and letting A approaching +∞. When A approaches +∞, this will give you a function similar to one of these :

I let you try the computation and identify which one corresponds to the Fourier transform of 1.
