Chapter 2 introduced first- and second-order linear time-invariant (LTI) systems in a very superficial way. A general form for the family of step responses, in the absence of input derivative terms, was presented for both types of systems. Alternate representations of LTI systems, namely, simulation diagrams and state-space models, were also discussed.
Chapters 1 and 3 outlined methods for transforming continuous-time differential equation models into discrete-time system models comprising difference equations. In doing so, the grounds were laid for the foundation of continuous-time system simulation.
A natural question that arises is “How accurate is the simulation?” In the case of continuous-time ...
