17.7 ADVANCED TOPICS
17.7.1 Input Functions
In some cases a system input function is comprised of many different functions, as shown in Figure 17.32. The step function can be used to switch function on and off to create a piecewise function. This is easily converted to the s-domain using the e-to-the-s functions.
17.7.2 Initial and Final Value Theorems
The initial and final values an output function can be calculated using the theorems shown in Figure 17.33.
