Question 1
Consider a sequence defined as x[n] = n * (0.5)^n * u[n]. Determine its Z-Transform and identify the ROC.
💡 Hint: Use the properties of geometric series for simplification.
Question 2
A signal x[n] is described as x[n] = {1, 2, 3, 0, 0, ...}. Compute the Z-Transform and discuss its implications for ROC.
💡 Hint: Look at how finite sequences behave in the Z-domain.
