Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider two signals x[n] = {1, 2, 3} and h[n] = {4, 5}. Calculate the convolution in both orders and confirm commutativity.

💡 Hint: Use the convolution formula.

Challenge 2 Hard

Describe a scenario where reversing the order of operations in a system leads to different outcomes. Discuss why this occurs.

💡 Hint: Explore the definitions of linear and non-linear systems.
