Find the Fourier transform of a one-dimensional rectangle function, and sketch the pair. Show how they can both be delta functions Verify that the FT of a Gaussian is a Gaussian, t2 1 202 2/o2 /2πο2 -x212 s its and so with a2=1, except for the constant 1/V2TT , e own Fourier transform. Show that they can both be delta functions (but not at the same time!). Sketch the transform cases for large and small variance. Note there are several books of cute Fourier transforms! Explain the relationship to the Laplace transform. (Note the use of a contour integral for this.)
