Question 1
What does the Time Shifting Property state?
- It changes the amplitude only.
- It multiplies the transform by an exponential factor.
- It does not affect the transform.
π‘ Hint: Think about how time changes the signal representation in the transform domain.
Question 2
True or False: A signal x(t) can be represented as x(t - t0) without needing the unit step function.
- True
- False
π‘ Hint: Consider the conditions under which the signal is defined.

Challenge Problems
Push your limits with challenges.
Question 1
A signal x(t) = e^{2t}u(t) undergoes a delay of 4 seconds. Compute its Laplace Transform and state its significance.
π‘ Hint: Apply the standard transform first, then consider the effect of the delay.
Question 2
For a delayed signal x(t) = cos(Οt)u(t) that is shifted by 3 seconds, find the Laplace Transform and clarify the relevance of the unit step function.
π‘ Hint: Remember to first express the cosine transform before applying the delay factor.
