Q. From the following graphs of the generalized transfer function 1/s+a, which plot shows a transfer function with a bigger value of a?
✅ Correct Answer: (D)
purple plot
Explanation: as the value of a increases, the inverse laplace transform of the given transfer function suggests that the e-at value is reducing. hence for a higher a, the graph reaches a 0 earlier. from the given figure, the purple plot reaches the steady state faster so purple plot is correct only.
