Analog and Digital Communications

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 table of contents introduction signal analysis using the fourier transform probability, random variables and random processes transmission of signals through communication channels amplitude modulation angle modulation analog communication systems signal sampling analog pulse communication information theory and source coding methods digital baseband transmission and reception digital passband transmission and reception advanced digital transmission methods information theory and error control coding working in the laboratory working with computers
