Unlike a traditional book, this text contains the theory of both analog and digital communication systems supported by simulations (MATLAB & Mathcad) and video lectures referenced throughout the chapters. These simulations and videos are accessed via its associated app, "Communication Systems", in the iOS and Android app stores. Samples of the book, videos, simulations and app details are available on http: //book.janaksodha.com
Based on the experience of lecturing for over eighteen years, this text begins with Fourier analysis, power and bandwidth, spectral density and random processes through a linear system to provide a solid foundation for the theory to be presented in the chapters to follow. An appendix on probability theory is also included with supporting simulations. Its only by interacting with the theory through different means (mathematical theory, problems with solutions, simulations with the option to modify parameters) can one begin to gain a deeper understanding of the underlying concepts and limitations.
