How to graph fourier transform
My question isn't on how they got the transform, my question is
how the graph was calculated, I don't know what sinc means
Note: 1) In the following problem set a notation Pa(t) is used to denote an even pulse (i.e. rectangular) shape function with the duration of a. This means that for example the function x(t) in question number one is 2P2(t-1). It is clear that using the properties of Fourier transform is greatly...
