This book serves as a guide for technicians in the electrical engineering industry. Organized into 14 chapters, this volume starts with an overview of the definition of wave motion, which is a significant concept in the study of communications methods. This text then explains decibel as the most convenient practical unit based on logarithms. Other chapters consider the frequency ranges for speech and music. This book describes as well the harmonic composition of sound waves and the frequency analysis of speech. The final chapter presents the fundamental feature of all telegraph systems, which is the use of codes such as the Morse code, cable code, and the five-unit even-length code. This book is a valuable resource for electrical technicians engaged in radio communications. Senior technicians on national certificate courses will also find this book extremely useful.
