Shu- Park chan International Technological University T HIS SECTION PROVIDES A BRIEF REVIEW of the definitions and fundamental concepts used in the study of linear circuits and systems. we can describe a circuit or system, in a broad sense, as a collection of objects called elements(components, parts, or subsystems) which form an entity governed by certain laws or constraints. Thus, a physical system is an entity made up of physical objects as its elements or components. A subsystem of a given system can also be considered as a system itself. A mathematical model describes the behavior of a physical system or device in terms of a set of equations, gether with a schematic diagram of the device containing the symbols of its elements, their connections, and numerical values. As an example, a physical electrical system can be represented graphically by a network which includes resistors, inductors, and capacitors, etc as its components. Such an illustration, together with a set of linear differential equations, is referred to as a model system. Electrical circuits may be classified into various categories. Four of the more familiar classifications (a)linear and nonlinear circuits, (b)time-invariant and time-varying circuits, (c) passive and active circuits, and(d)lumped and distributed circuits. A linear circuit can be described by a set of linear(differential) uations; otherwise it is a nonlinear circuit. A time-invariant circuit or system implies that none of the components of the circuit have parameters that vary with time; otherwise it is a time-variant system. If the total energy delivered to a given circuit is nonnegative at any instant of time, the circuit is said to be passive otherwise it is active. Finally, if the dimensions of the components of the circuit are small compared to the wavelength of the highest of the signal frequencies applied to the circuit, it is called a lumped circuit; otherwise it is referred to as a distributed circuit There are, of course, other ways of classifying circuits. For example, one might wish to classify circuits according to the number of accessible terminals or terminal pairs(ports). Thus, terms such as n-terminal circuit and n-port are commonly used in circuit theory. Another method of classification is based on circuit configu rations( topology), which gives rise to such terms as ladders, lattices, bridged-T circuits,etc As indicated earlier, although the words circuit and system are synonymous and will be used interchangeably throughout the text, the terms circuit theory and system theory sometimes denote different points of view in the study of circuits or systems. Roughly speaking, circuit theory is mainly concerned with interconnections of ircuit topology) within a given system, whereas system theory attempts to attain generality by means of abstraction through a generalized (input-output state)model. One of the goals of this section is to present a unified treatment on the study of linear circuits and systems That is, while the study of linear circuits with regard to their topological properties is treated as an important phase of the entire development of the theory, a generality can be attained from such a study. The subject of circuit theory can be divided into two main parts, namely, analysis and synthesis. In a broad sense,analysis may be defined as"the separating of any material or abstract entity [system] into its constituent elements; "on the other hand, synthesis is"the combining of the constituent elements of separate materials abstract entities into a single or unified entity [system]- 2 It is worth noting that in an analysis problem, the solution is always unique no matter how difficult it may be, whereas in a synthesis problem there might exist an infinite number of solutions or, sometimes, none at all! It should also be noted that in some network theory texts the words synthesis and design might be used interchangeably throughout the entire discussion of the subject. However, the term synthesis is generally used to describe analytical procedures that can usually be carried out step by step, whereas the term design includes practical (design) procedures(such as trial-and-error techniques which are based, to a great extent, on the experience of the designer)as well as analytical methods. In analyzing the behavior of a given physical system, the first step is to establish a mathematical model. This model is usually in the form of a set of either differential or difference equations (or a combination of them), Circuit topology or graph theory deals with the way in which the circuit elements are interconnected. A detailed discussion on elementary applied graph theory is given in Chapter 3. 6 The definitions of analysis and synthesis are quoted directly from The Random House Dictionary of the English Language, 2nd ed, Unabridged, New York: Random House, 1987. e 2000 by CRC Press LLC
