How can the Z-transform be used to analyze stability in discrete time systems?

By examining the region of convergence (ROC) of the system's transfer function. If the ROC includes the unit circle in the Z-plane, then the system is stable.

By checking the real part of the poles of the system's transfer function.

By analyzing the phase margin of the system's transfer function.

By evaluating the magnitude response of the system's transfer function.
