Can z transform be negative
Webwith the Z-transform . Substituting z= rej!^ in the Z-transform , X(z) = X1 n=1 (x[n]r n)e j!n^; reveals that the Z-transform is just the DTFT of x[n]r n. If you know what a Laplace transform is, X(s), then you will recognize a similarity between it and the Z-transform in that the Laplace transform is the Fourier transform of x(t)e ˙t. Hence ...
