WebRectangular periodicity, as considered here, allows an easy generalization. As in the 1-D case, we note that regular convolution is not possible with periodic sequences, since they have infinite energy. We offer next a proof of the periodic convolution property. Proof of property 2: Let Then with . Thus by periodicity, as was to be shown.
