Question 1
Given X(s) = (4s + 8)/(s^2 + 4s + 4), apply the PFE method to find the coefficients and perform the inverse Laplace Transform.
π‘ Hint: Pay attention to repeated roots during decomposition.
Question 2
For the function X(s) = (s^2 + 2s + 5)/(s^2 + 4), determine the PFE considering complex poles, and calculate the inverse transform.
π‘ Hint: Remember to handle the complex conjugate poles as a single quadratic expression.
