ABSTRACT
In Chapters 5 and 6 we discussed the derivation of equations and their solutions, respectively. During the discussion of solutions, we have used standard analytical solutions of generic fi rst and second order systems and have talked about the interpretation of the solutions. We also talked about the conclusions one might draw about system behavior from the nature of the solution, both in the time domain and in the frequency domain. While that vital discussion provides us with a sound footing in interpreting the results, the actual simulation problem that we encounter every time will involve a new set of differential equations and, more often than not, a numerical technique will be necessary for its solution.
