Grami organizes the book to follow the logical signal flow of a typical digital communication system. Beginning with foundational concepts of signals, systems, and probability theory, the text gradually progresses through source coding, baseband transmission, and passband modulation. This linear progression is one of the book’s key pedagogical assets. Unlike some texts that jump erratically between modulation and coding, Grami ensures that each chapter builds directly upon the previous one. For instance, the introduction of the matched filter is immediately followed by a thorough discussion of error probability detection, allowing students to see the cause-and-effect relationship between receiver design and system performance. : Focuses on the "why" and "how" of
