Challenge Problems
Push your limits with challenges.
Question 1
Given a system that uses a unit delay to process an input signal, how would the output change if the input is shifted one time unit backwards? Illustrate with equations.
💡 Hint: Consider how calendrical shifts change event timings.
Question 2
Discuss the implications of not having a unit delay in a recursive system design and what issues might arise.
💡 Hint: Reflect on systems without memory—how would they function?
