Does it? Perhaps I am misunderstanding convolution altogether.
I have always learned it from the control standpoint, as being 
x(n)*y(n) =
the infinite summation of x(k)y(n-k) from k=-infy to k=infy for all n.

This would imply the same dimension, n, would it not?
Am I missing something?
Does anyone have any links that explain why the dimension changes? 

thx,
NZG.
