We are delighted to present the textbook titled “EL-212: IKS – Ancient
Communication Technology and Modern Electronic Communication”,
which is crafted in alignment with the new curriculum under the National
Education Policy (NEP) 2020. This book is a unique blend of India’s rich ancient
knowledge systems and the principles of modern electronic communication,
offering students a holistic view of how communication has evolved through
time.
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.
We express our sincere thanks to Mr. Rangrao Patil, Prashant Publication,
Jalgaon, for his continued support, encouragement, and valuable contribution in
bringing this book to fruition. His dedication to promoting quality educational
materials is truly commendable.
We welcome suggestions and feedback from teachers and students for the
further improvement of this textbook.
