What is Roc?
If we use control systems topic here.
The system is stable because all poles are lying on the right-hand side.

The ROC for the non causal signal is? Can anyone answer this?

Find ROC by using partial differentiating it gives two poles both are causal so the greatest pole is roc that means z>2, should lie outside the circle. It is unstable.

The system is unstable as the poles are not inside ie. Z<I1I Not satisfies.

System is unstable as ROC doesn't encircle unit circle.

The pole Z=2 lies outside the unity circle. Then how can we say it as stable ?

One of the pole z=2 lies outside the unit circle, so the system is unstable.

Pole doesn't lies b/w the circle so the system is not stable.

The pole Z=2 lies outside the unitcircle. The ROC is not mentioned in this question so the system is unstable.
