Basic Concepts: Linear Two-Ports with Memory and Higher-Order Linear Circuits

In this chapter, we introduce a two-port component with memory, called coupled inductors. The dynamics of higher-order circuits are analyzed by resorting to the complementary component representation and to the state variables method, thus generalizing the concepts introduced for first-order circuits. Methods for the analysis of stability and for finding the circuit response to various inputs, including also discontinuous functions, are provided.
