Time Domain Description of Linear Systems

Abstract

In Chapter 2 we studied behaviors described by equations of the form $R(\frac{d}{{dt}})w = 0$ . We obtained fundamental properties such as linearity, time-invariance, and the like, as well as the relation between the behavior and its representations. What we did not do, however, is pay attention to what the trajectories in the behavior, the weak solutions of $R(\frac{d}{{dt}})w = 0$, actually look like.
