The main theme of the book Introduction to Communication Sciences is to provide information on (a) communication, language, speech & their components in brief with illustrations, (b) production, characteristics and generation of sound in detail, (c) sound intensity and concept of decibel, (d) hearing mechanism, audibility and hearing, and (e) introduction to the field of speech-language pathology and audiology including historical aspects of these two fields in five chapters. It is primarily written for libraries and with an intention of helping students studying in the first year of the speech and hearing Bachelor's programme, master's students in Speech Pathology, research scholars, and faculty teaching Speech Pathology and Audiology. The book is different from others as it incorporates literature from ancient Sanskrit literature and includes several illustrations for ease of understanding. It incorporates definitions of speech, language, communication, and their components, functions of communication, normal development of speech & language, pre-requisites and factors affecting speech-language development, cultural and linguistic issues in communication; bi/multilingual issues. It addresses overview of speech production, speech mechanism, the acoustic theory of speech production, and bases of speech and language. In addition, the book focuses on acoustic energy and power, absolute and relative units and measurements, Bel and deciBel, sound pressure and decibel sound pressure levels, and characteristics and application of decibels. Hearing mechanism, audibility and hearing is also dealt with along with hearing range, procedures of estimating minimum audible levels, minimum audible pressure and field, reference equivalent threshold sound pressure levels and hearing levels, and other related issues. Finally, it introduces the historical aspects of the field of Speech-Language Pathology and Audiology, development of the field in global context, interdisciplinary nature of the field, development of instrumentation in the field, and scope of practice of the field. As historical aspects are dealt with, material from WWW were included and hence internet references were inevitable. The course is required / hard core / discipline specific core course, and hence the proposed book would be used as a primary text. With its reader-friendly content and valuable online resources, Introduction to Communication Sciences is an ideal text for beginning speech pathology and audiology students and faculty.

An accessible undergraduate textbook introducing key fundamental principles behind modern communication systems, supported by exercises, software problems and lab exercises.

This volume provides a graduate-level introduction to communication science, including theory and scholarship for masters and PhD students as well as practicing scholars. The work defines communication, reviews its history, and provides a broad look at how communication research is conducted. It also includes chapters reviewing the most frequently addressed topics in communication science. This book presents an overview of theory in general and of communication theory in particular, while offering a broad look at topics in communication that promote understanding of the key issues in communication science for students and scholars new to communication research. The book takes a predominantly "communication science" approach but also situates this approach in the broader field of communication, and addresses how communication science is related to and different from such approaches as critical and cultural studies and rhetoric. As an overview of communication science that will serve as a reference work for scholars as well as a text for the introduction to communication graduate studies course, this volume is an essential resource for understanding and conducting scholarship in the communication discipline.

This book provides a clear and easy to follow treatment of communications and networking. It is written specifically for undergraduates who have no previous experience in the field. The author takes a step-by-step approach, with many examples and exercises designed to give the reader experience and increase confidence by using and designing communications systems. Written by a lecturer with many years' experience teaching undergraduate programmes, the text takes the reader through the essentials of networking and provides a comprehensive, reliable and thorough treatment of the subject. The book is also accessible for business professionals.

There are many valuable and useful books on electrical communication (References 1-5 are some examples), but they have certain disadvantages for the beginner. The more advanced books present some things in a basic way, but they are very narrow for an introduction to communica tion. The introductory books are broader but still narrow by our stan dards. Further, they often pick things out of thin air rather than derive them. This book is aimed at giving the beginner a basic understanding of a wide range of topics which are essential in communication systems. These include antennas and transmission, thermal noise and its consequences, Fourier transforms, modulation and noise, sampling and pulse code modulation, autocorrelation and power spectrum, optimum filtering, gauss ian noise and errors in digital transmission, data transmission, limits on data rate including information theory and quantum limits, and source encoding. We have not included communications traffic, switching, and multiplexing, nor protocols for digital and computer communications. For these, Reference 6 is excellent. In general, our book does not discuss the circuits used for communication or the physics of radio propagation. We assume that these will be taught in specialized courses, but such courses are not prerequisites for this one. Chapter 1 introduces the transmission formula or antenna equation and antenna directivity. Only a very basic sophomore physics knowledge of electromagnetic theory is assumed. The radar equation is also treated.

Introduction to Digital Communications explores the basic principles in the analysis and design of digital communication systems, including design objectives, constraints and trade-offs. After portraying the big picture and laying the background material, this book lucidly progresses to a comprehensive and detailed discussion of all critical elements and key functions in digital communications. - The first undergraduate-level textbook exclusively on digital communications, with a complete coverage of source and channel coding, modulation, and synchronization. - Discusses major aspects of communication networks and multiuser communications - Provides insightful descriptions and intuitive explanations of all complex concepts - Focuses on practical applications and illustrative examples. - A companion Web site includes solutions to end-of-chapter problems and computer exercises, lecture slides, and figures and tables from the text
