Chapter 13 Two-port networks 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 interconnection of two- port and introduce the Nic.(负阻抗变换器)and Gyrator(回转器

A pair of terminals at which a signal may enter or leave a network is called a port The four-terminal network input output When i=i, and i,= a two-port network The two-port is composed of linear elements, including dependent sources but not containing any independent Sources
