Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does linearity in an LTI system mean?
- The output depends only on past inputs.
- The output is proportional to the input.
- The output is independent of the input.
💡 Hint: Consider the effect of multiplying your input by a constant.
Question 2
True or False: A time-invariant system's response changes over time.
- True
- False
💡 Hint: Think about a clock—what happens when you push the instant replay button?

Challenge Problems
Push your limits with challenges.
Question 1
Design an LTI system that translates an input signal into an output where the peak value is cut in half and then shifted by 2 units to the right. Explain how you would account for linearity and time-invariance.
💡 Hint: Think about how you would change the input signal mathematically before analysis!
Question 2
Discuss a real-world scenario in which an LTI system approximation might fail and the implications this has on predictions.
💡 Hint: Consider audio engineering principles and how they deviate with extremes.
