This work features experiments based on the knowledge taught in "Electronic Principles", which is designed for use in courses such as electronic devices or electronic circuits. This edition features a new chapter on communication circuits, as well as performance objectives for each chapter. New material provides a stronger theoretical understanding of electronics. In addition, special sections called "T-shooters", designed to strengthen students' trouble-shooting skills, are included throughout the text. The content of the work has also been updated to keep coverage in step with the fast-changing world of electronics. Each chapter offers multi-level question groups oriented to theory, design and trouble-shooting. Additional higher-level problems are provided for students in advanced programmes.
