The book is divided into several chapters, each focusing on a specific aspect of communication systems. The initial chapters introduce the basic concepts of communication systems, including signals, systems, and noise. The subsequent chapters delve into the details of analog communication systems, such as amplitude modulation, frequency modulation, and pulse modulation. The book also covers digital communication systems, including digital modulation, coding, and transmission.
Dr. Sanjay Sharma’s Communication Systems (Analog and Digital)
The textbook is divided into two primary sections, taking a "bottom-up" approach that begins with fundamental signal analysis before moving into complex modulation schemes.
: Includes dedicated chapters on Information Theory, Error Control Coding, and Signal Space Analysis. Student-Centric Pedagogy : The book is divided into several chapters, each
The term "exclusive" often implies rarity, but in the context of Sanjay Sharma’s work, it refers to the unique, student-centric approach that separates it from standard textbooks.
Each chapter concludes with short-answer questions, long-form theory questions, and unsolved numerical problems to test comprehension. 4. Competitive Exam Relevance (GATE, IES, and Beyond)
Every communication system, regardless of complexity, consists of three primary elements: : Includes dedicated chapters on Information Theory, Error
Intercepts the transmitted signal from the channel and processes it to reconstruct the original message signal. This involves demodulation, decoding, and filtering. 2. The Role of Noise and Distortion
As technology evolved, digital communication became dominant due to its ruggedness against noise and ease of data encryption. Dr. Sanjay Sharma’s book transitions smoothly into digital techniques, highlighting how continuous signals are converted into discrete bits. Sampling and Quantization
While the physical 7th edition is available for purchase through retailers like Amazon or AbeBooks , various digital versions are hosted online: Sanjay Sharma's Communication Systems PDF - Scribd and Cellular Communication systems .
The book "Communication Systems: Analog and Digital" by Sanjay Sharma provides a comprehensive coverage of the fundamental principles and concepts of communication systems, including both analog and digital systems. The author has taken a meticulous approach to present the subject matter in a clear, concise, and easy-to-understand manner, making it an ideal resource for readers with varying levels of expertise.
Analog communication focuses on continuous signals. The book provides in-depth coverage of how these signals are modulated to travel long distances.
The book also covers state-of-the-art technologies, including , Spread-Spectrum systems , and Cellular Communication systems .
: The book is praised for its easy-to-understand language and use of numerous illustrations to simplify complex concepts.
