Question
Solution
It seems like you're asking about the Region of Convergence (ROC) in Z-transform for a two-sided sequence. The ROC of a Z-transform for a two-sided sequence is the entire z-plane except at z=0 and z=∞.
Here's a step-by-step explanation:
-
The Z-transform is a mathematical tool used in signal processing and control theory. It's used to analyze and represent discrete-time signals.
-
The Region of Convergence (ROC) is a region in the z-plane for which the Z-transform summation converges.
-
For a two-sided sequence, the ROC does not include the point z=0 and z=∞. This is because a two-sided sequence extends from negative infinity to positive infinity, and the Z-transform summation would not converge at these points.
-
Therefore, the ROC of a Z-transform for a two-sided sequence is the entire z-plane except at z=0 and z=∞.
