This is the only book on the market that has been conceived and deliberately written as a one-semester text on basic electric circuit theory. As such, this book employs a novel approach to the exposition of the material in which phasors and ac steady-state analysis are introduced at the beginning. This allows one to use phasors in the discussion of transients excited by ac sources, which makes the presentation of transients more comprehensive and meaningful. Furthermore, the machinery of phasors paves the road to the introduction of transfer functions, which are then used in the analysis of transients and the discussion of Bode plots and filters. Another salient feature of the text is the consolidation into one chapter of the material concerned with dependent sources and operational amplifiers. Dependent sources are introduced as linear models for transistors on the basis of small signal analysis. In the text, PSpice simulations are prominently featured to reinforce the basic material and understanding of circuit analysis.Key Features* Designed as a comprehensive one-semester text in basic circuit theory* Features early introduction of phasors and ac steady-state analysis* Covers the application of phasors and ac steady-state analysis* Consolidates the material on dependent sources and operational amplifiers* Places emphasis on connections between circuit theory and other areas in electrical engineering* Includes PSpice tutorials and examples* Introduces the design of active filters* Includes problems at the end of every chapter* Priced well below similar books designed for year-long courses

One would rarely have the opportunity to augment his medical library with a more exhaustive examination of the subject matter than is contained herein. Would only that all areas of one''s professional responsibilities be available in such a complete, didactic, written form. Having a decided interest in the subject of head and neck paragangliomas for the past decade, I have had the opportunity to explore the subject through published medical literature and personal investi­ gation, and feel qualified to commend Doctors Zak and Lawson on their dedica­ tion, accuracy, and thoroughness in this presentation. One seeking any particular aspect of knowledge from historical to an up-to-date concept on the subject of paragangliomas will find his answer here. Vincent J. Hyams CAPT MC USN Chairman, Otolaryngic Pathology Department Armed Forces Institute of Pathology Washington, D.C. Preface One of us (F.G.Z.) initially became interested in the paraganglionic system when as a resident in pathology at The Mount Sinai Hospital, he performed an autopsy on an elderly woman with an intracranial tumor of the posterior fossa, which extended through the jugular foramen into the neck in a dumbbell fashion.
