Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a Z-transform of X(z) = (2)/(z^2 - z - 2), use Partial Fraction Expansion to find the time-domain signal x[n].

💡 Hint: Don't forget to identify and factorize correctly.

Challenge 2 Hard

Using Contour Integration, derive the Inverse Z-Transform for X(z) = z/(z^2 + 1), highlighting the contour path.

💡 Hint: Visualize the complete contour path for clarity.
