1.31. In this problem, we illustrate one of the most important consequences of the prop- erties of linearity and time invariance. Specifically, once we know the response of a linear system or a linear time-invariant (LTI) system to a single input or the responses to several inputs, we can directly compute the responses to many other input signals. Much of the remainder of this book deals with a thorough exploitation of this fact in order to develop results and techniques for analyzing and synthesizing LTI systems. (b) Determine and sketch the response of the system considered in part (a) to the input x3 (1) shown in Figure P1.31(d).

You can check with this but you must demonstrate the other processes.
