About this eBook
PREFACE TO THE REVISED SEVENTH EDITION The revised edition of this book provides a comprehensive coverage of the latest topics of the field of electronics communication. Although nothing has been omitted from the previous edition there are significant addition of the topics such as Cellular Mobile Communication, Digital Data Communication, Computer Communication, Radio Paging System, DTH, IPTV, Wi-fi, Consumer Electronics and Advanced Communication Systems. The revised edition is presented in simple and easy to understand language with more illustrations. This revised edition meet the latest syllabus of different engineering colleges and universities. The book is quite useful for students preparing for various courses in communication Engineering, professional like Engineering services etc. The book is equally useful to the students of B.Sc, M.Sc. and M. Tech. Electronics . A good numbers of valuable suggestions were received from the subject experts which has been incorporated in this edition. I am thankful to Dr. H.S. Shiveram, Head Communication, NIE, Mysore, Prof. D.P. Chakraborthy, MPCT Gwalior M.P . Shri N.L. Narayan, MIT Aurangabad, Shri S.P. Singh, Controller, BTE, Delhi. M.S. Mageshwari, Niketan Engg.

PREFACE TO THE FIRST EDITION The main objective of the book is to bring out broad outlines of different types of electronic communication systems. The book presents to the students of Communication Engineering information about the basic processes, principles and philosophies of different communication systems. The book will be quite useful for students preparing for various courses in Communication engineering, professional like Engineering services etc. It can also prove equally useful to the students of M.Sc. Electronics . The first four chapters of the text describe different types of signals, modulation and demodulation of these signals, various transmission channels and noise encountered by the signals during propagation from sender to receiver end. Apart from this, this part of the book also deals with different forms of line communication systems. A brief introduction of information theory is also given at the end of the text so that the students become familiar with this aspect of communication systems. Radio communication systems form the next part of the book and is dealt with in Chapter V and VI under the headings Radio Transmission Systems and Radio Receivers. Different forms of radio communication systems such as SSB ISB, telegraphy telephony FM PM and the problems encountered in these systems are discussed and possible solutions are also presented in brief. Broadband communications and Picture signal transmission reception forms the last part of the book. Broadband communications are covered under the topics like FDM TDM, wire microwave circuits. Lastly satellite and optical communication systems are also outlined briefly. In Picture signal systems are included topics like Facsimile, black and white colour TV principles. This discussion, however, is limited to systems presently operating in India. It is hoped that the book will meet the long felt needs of different categories of students. While every care has been taken to present an error-free text, but some unintentional errors might have crept in at various stages and readers are requested to point out these errors. Suggestions for improvement of the text of this book will be most welcome. The author is thankful to friends and colleagues who have helped in preparation of the text and
