In the chapter we shall study the properties of second-order circuits, i.e., circuits containing two energy-storage elements. Such circuits will, in general, be characterized by second-order differential equations

1. Nonlinear resistor A nonlinear resistor is an element whose voltage and current are related by a nonlinear equation

In this chapter we will introduce an important frequency is that network function or parameter reaches a maximum value. In certain simple a networks, this occurs when an impedance or admittance is purely real-a condition known as resonance

In this chapter we shall investigate some ways of characterizing two-port networks. Before we do this, we must consider some of the more general details that apply to all networks which have two port. In addition, we shall consider interconnec of two-

In the chapter we shall begin to look at more general and more powerful methods of circuit analysis -the Laplace transform techniques

In the chapter we first shall consider the nodal analysis and introduce the networks containing dependent sources. In addition later in the chapter we shall consider state(状态)- variable analysis
