Challenge Problems
Push your limits with challenges.
Question 1
How would the Laplace transform of a system change if instead of an ideal impulse, we had a finite duration pulse? Provide the transformation.
💡 Hint: Look deeper into how the finite pulse affects the integral.
Question 2
Critique the assumption of using the Dirac delta function in numerical simulations. How could approximating it lead to complications?
💡 Hint: Consider numerical methods for approximating impulses.
