I have some trouble with a image processing system I am developing.

I'm not sure of my FFT's - convolutions doesnt come out as I expect them.

What would be very welcome is three pictures 1 2 3 where 3 is

the convolution of 1 and 2 and where 1 is a spike and 2 is a nonsymmetrical

simple shape. Then I can use those as a check that I do the right thing!

You wouldnt know of such an example? If you do please let me know!
