'The field of communication engineering is witnessing sweeping changes and this trend will continue. With change being a constant, focus on the fundamentals is very important as it enables students in coping with the ever evolving technology. Meant for the undergraduate students of electronics and communication engineering, this textbook on "Analog and Digital Communications: Theory and Lab Work" focuses on the fundamental concepts with emphasis on practical applications. The book also facilitates the student to become a complete communications engineer who needs to master three areas - application of mathematics, circuit design and testing, and communication system simulation using software. The content of the book is divided into four parts: Part I: Fundamentals Part II: Analog Communications Part III: Digital Communications Part IV: Lab Work
' Focus on basic concepts with balance between mathematical analysis and practical aspects Emphasis on demystifying the working of communication systems Practical information about both American and Indian systems Unique way of explaining digital communication systems (baseband and modulated) Guidelines on using analog and digital oscilloscopes and spectrum analyzer Circuit projects for "build-and-test" assignments Simulation programs using Scilab. Scilab is an open-domain programming language similar to MATLABÒ Exercises are embedded in text for consolidation of concepts, extension of topic, and for self-study Questions and problems are provided at the end of chapters to help students sharpen their understanding of the subject
