You mean the inverse of sinc is a rect (or box) function. The other function is cosinc which you'll need to find a way to invert.
Can someone tell me how to calculate the inverse fourier transform of sin(3w)*cos(w)/(w^2)
I know that 2sin(aw)/w has an inverse fourier transform that is 1 when -a<t<a and zero otherwise and therefore the inverse fourier should be the convultion of two of these and some other thing...can you help me?
OK, just wantd to be sure it wasn't a typo. I'm still thinking about how to do this and Opalg's comment. It should be pointed out that the Fourier transform of is which also seems to have a non-integrable singularity at .
