This paper introduces a canonical graph signal model defined by a canonical graph and a canonical shift, the companion graph and the companion shift. These are canonical because, under standard conditions, we show that any graph signal processing (GSP) model can be transformed into the canonical model. The transform that obtains this is the graph z-transform (GzT) that we introduce. The GSP canonical model comes closest to the discrete signal processing (DSP) time signal models: the structurearXiv:2203.13791v1 fatcat:mci63yfa2vbelb6i6cxtygjlcu
