WebJan 6, 2024 · 1 Answer Sorted by: 4 The Z-transform of a sequence a n is defined as A ( z) = ∑ n = − ∞ ∞ a n z − n. In your case, A ( z) = 1 / z = z − 1, so this must mean a n = 0 for all n ≠ 1, and a 1 = 1. We don't need any fancy computations in this example, we just read off the one nonzero coefficient directly from A.
