This textbook provides a thorough coverage of basic electrical and electronic theory at a level which is easily understood by the student who does not have a knowledge of advanced mathematics. Following the chapters explaining fundamental theory, the applications to electrical and electronic systems are described. Although a detailed study of advanced electronic systems is beyond the scope of the text, the last several chapters are devoted to descriptions of many of these systems as installed in modern aircraft and space vehicles. These systems are usually described as avionic systems, inasmuch as they represent aviation electronics. With the background knowledge obtained in earlier chapters, a student is able to understand the electronic systems in.
