The book begins with an exploration of Ancient Indian Knowledge Systems (IKS) and Communication, highlighting the scientific and technological wisdom embedded in our heritage. This includes early forms of communication such as oral traditions, script development, signalling methods, and the philosophical understanding of sound and transmission. The second part of the book focuses on the Basics of Electronic Communication, providing foundational knowledge about communication systems, their components, and modes of transmission. The final sections deal with Amplitude Modulation, Angle Modulation, and Analog Pulse Modulation, covering their principles, waveforms, generation, and detection techniques.
Our goal is to make this textbook student-friendly, engaging, and informative. It has been written in simple language, supplemented with illustrations, block diagrams, and examples to enhance understanding. The book is suitable not only for undergraduate students but also for anyone interested in exploring the roots of communication alongside modern technology.
