Ebook: Network Analysis And Synthesis

In the second edition, I have tried to keep the organization of the first
edition. Most of the new material are additions aimed at strengthening
the weaknesses of the original edition. Some specific changes deserve
mention. The most important of these is a new chapter on computer
applications (Chapter 15). In the past five years, digital computers have
brought about many significant changes in the content of engineering
subject matter concerned with both analysis and design. In analysis,
computation has become an important adjunct to theory. Theory establishes
the foundation of the subject matter; computation provides clarity,
depth, and insight. In design, the computer has not only contributed
precision and speed to existing procedures but has made practicable
design methods that employ iteration and simulation. The importance of
computer-aided design cannot be overemphasized. In Chapter 15 I have
attempted to survey some digital computer applications in the areas of
network analysis and design. I strongly encourage all students to read
this chapter for cultural interest, if not for survival.
Another new section contains a rigorous treatment of the unit impulse.
It was difficult to decide whether to incorporate this m3~rial in Chapter 2
in the discussion of signals or in a separate appendix. By putting generalized
functions in an appendix, I have left the decision of whether to teach
the rigorous treatment up to the individual instructor.
Other changes worth mentioning are: (1) two new sections on the
Fourier integral in Chapter 3; (2) a section on initial and final conditions
in Chapter 5; (3) a section on Bode plots in Chapter 8; (4) revised
material on two-port parameters in Chapter 9; and (5) new sections on
frequency and transient responses of filters in Chapter 13. Major or
minor changes may be found in every chapter, with the exception of
Chapters 11 and 12. In addition, many new problems are included at the
end of each chapter.
