What is the inverse Z-transform of 1 z?

The Z-transform of a sequence an is defined as A(z)=∑∞n=−∞anz−n. In your case, A(z)=1/z=z−1, so this must mean an=0 for all n≠1, and a1=1. We don't need any fancy computations in this example, we just read off the one nonzero coefficient directly from A.

How do you find the Z-transform of 1?

Z transform has summation limits from -infinity to + infinity. x[n] =1 is not absolutely summable. Hence Z transform doesnt exist.

What is inverse Z-transform?

The inverse Z-transform is defined as the process of finding the time domain signal x(n) from its Z-transform X(z). The inverse Z-transform is denoted as − x(n)=Z−1[X(z)] Since the Z-transform is defined as, X(z)=∞∑n=−∞x(n)z−n⋅⋅⋅(1)

Definition of Z-Transform

In mathematics and signal processing, the Z-transform converts a discrete-time signal, which is a sequence of real or complex numbers, into a complex frequency-domain representation. Also, it can be considered as a discrete-time equivalent of the Laplace transform.
