Question 2.
Define a causal system.
Show hintHide hint
Consider time relations!
3Question 3.
What is the main limitation of the Fourier transform?
- It can only analyze periodic functions.
- It requires functions to be integrable over the entire real line.
- It cannot be used to solve differential equations.
Show hintHide hint
Think about the properties of integrable functions.
4Question 4.
True or False: Laplace transforms can handle functions that are not absolutely integrable over (-∞, ∞).
- True
- False
Show hintHide hint
Reflect on the time domains of these functions.
Question 5.
Develop a scenario where a Fourier transform fails to provide useful information due to the limitations. What would be a better approach?
Show hintHide hint
Think about systems responding to loads.
Question 6.
