This textbook covers the fundamental concepts of analog communications with a Q approach. It is a comprehensive compilation of numerical problems and solutions covering all the topics in analog communications. Richly illustrated with figures, this book covers the important topics of signals and systems, random variables and random processes, amplitude modulation, frequency modulation, pulse code modulation and noise in analog modulation. It has numerical questions and their solutions clearing the concepts of Fourier transform, Hilbert transform, modulation, synchronization, signal-to-noise ratio analysis and many more. All the solutions have step-by-step approach for easy understanding. This book will be of great interest to the students of electronics and electrical communications engineering.
