Hi,
I have a problem determining the ROC of a z transform.
In the first place, I can't understand fully the definition of ROC.
My teacher says it is the value for which x(z) should not be zero or negative.
I've been applying this equation: x(z) > 0 in my quizzes and exams
From the equation I have above, it is so clear that I get values for z that makes x(z) not zero and non-negative.
But I always get ROC wrong. Can someone please clarify what ROC means and how to get it.
Thank you.
