Electronics 2 Checkbook is an 11-chapter text that presents problems and worked examples to establish and exemplify the theory contained in technical syllabuses, with a particular emphasis on electronics. The introductory chapters review the elementary theory of semiconductors and the p-n junction diode. The subsequent chapters deal with the applications of diode, the characteristics of bipolar transistors, and the mode of operation of small signal amplifiers. These topics are followed by discussions of the function of the field-effect transistor and power supplies. The concluding chapters explore the principles of combinational logic gate elements, the Karnaugh mapping, and the sequential logic systems. This book will be of great value to students seeking technician or equivalent qualification through the courses of the Business and Technician Education Council.
