WebNov 5, 2016 · One should also know that a rectangular function in one domain of the Fourier transform is a sinc-function in the other domain. So from a first glance we should be able to tell that the resulting spectrum is composed of two sinc-functions, one shifted to the positive and the other to the negative frequency of the cosine. Finally, it should be ...
