เนื้อหาย่อ : Id of science must in some manner pay tribute to electronics. I wealth of material and the number of contributors to this technology it be- es a formidable task for the individual scientist to keep abreast of the advances To compensate somewhat for this problem the Department of hns Hopkins University has, for a number of years, offered urse in electronics at an advanced level to students in physics, chemistry, bio- pbysics, biology, and engineering. The emphasis in this course has been placed ndamentals; the assumption has been that an understanding of th tal concepts would prepare the student for the many special applications which might encounter in his future research work. In order to provide adequate coverage of passive circuits, physical electronics, electronic circuits, fairly sophisticated mathematical methods were essential. er a period of years a presentation has evolved which entails a concentrated dy of operational methods as applied to passive networks. Many concepts such symptotic behavior of frequency responses, pulse response, and matrix analysis are fully developed in conjunction with the st sive circuits. Such concentration in rather obvious areas seems to li load later in the study of active circuits. three volumes presented under the title Fundamentals of El present the content of this course. In fact the material presented here has been tially expanded over that which could be conveniently presented in a two- ester course. This was done to achieve completeness and to account for the that the course has not had a static content. In some years the material con- ing physical electronics has been emphasized at the expense of circuits, while other periods the reverse was true. The lectures are normally presented in conjunction with a laboratory. In order some cofrelation between the laboratory and the lectures, t rdinarily introduced with an initial six-week discussion of basic active circuits. erial for this introduction is found at the beginning of Volume III heading of Ideal Diodes, Triodes, and the Ideal Transistor Circuits. In other the students begin their studies with rough calculations employ ments. Concepts of self-biasing, cutoff, and saturation are available in this limit most convenient form. The introductory material in Volume I c rchhoff's Laws and the elements of the operational calculus are not essential to course. These sections were added to provide a rationale for the main body the text. najor aim of these volumes has been to provide the main topics a unified manner. As a result the techniques employed in Volun
