11.5%, as illustrated in Figure 4.27.The settling time is the time required for the sys-
tem output to settle within a certain percentage (for example, 2%) of the desired
steady-state output amplitude. We cover the notions of overshoot and settling time
more thoroughly in Chapter 5. The overshoot and settling times are summarized in
Table 4.2.
