1 oct 2003 · Property 2: The Fourier transform of x[n] converges absolutely iff the ROC of the z-transform of x[n] includes the unit circle Property 3: The ROC cannot contain any poles Property 4: If x[n] is a finite-duration sequence, then the ROC is the entire z-plane, except possibly z = 0 or z = ∞

The ROC cannot contain any poles If x[n] is finite duration (ie zero except on finite interval −∞ < N1 ≤ n ≤ N2 < ∞), then the ROC is the entire z-plane except perhaps at z = 0 or z = ∞ If x[n] is a right-sided sequence then the ROC extends outward from the outermost finite pole to infinity

The z-transform of a signal is an infinite series for each possible value of z in the So we have two possible distinct definitions for the ROC: “the z values where There cannot be any poles in the ROC, so all the poles must be inside (or on
