Network ElementsElectric networks of lumped impedances are composed of elements such as resistors, capacitors, inductors and transformers. The characteristics of such circuit elements were treated in Chapter 3. In the pages that follow it will be assumed that the elements and the networks are linear; that is, have constants and transmission characteristics that do not vary with the magnitude of either the voltage impressed or the current flowing (conf. Distortion). Any circuit containing coils with ferromagnetic cores will be non-linear, but this effect is assumed negligible. The elements and networks are considered bilateral, passing current and signals equally well in both directions. Networks containing rectifying elements that are unilateral will not be considered.
