Question 1

What defines a time-invariant system?

Its output changes with time
Its output does not change with time shifts
It is always linear

💡 Hint: Think about how the output relates to past inputs.

Question 2

True or False: A time-variant system produces the same output regardless of when the input is applied.

True
False

💡 Hint: Consider how shifting impacts the output.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Illustrate and analyze an example where a time-variant system fails to produce a predictable output while a time-invariant counterpart operates smoothly.

💡 Hint: Think about systems that depend on factors outside of the input.

Challenge 2 Hard

Create a mathematical model representing a time-invariant system, then modify it to turn it into a time-variant system. Discuss the implications.

💡 Hint: Consider ways to integrate time dependencies into your model.
