We must address the elephant in the room.
Since natural signals (voice, video) are analog, the text explains how to transform these into digital formats for processing and transmission. 3. Digital Baseband Transmission

This is the heart of the book. Grami excels here, explaining Quadrature Amplitude Modulation (QAM) using constellation diagrams that are far clearer than those in Proakis’s text. We must address the elephant in the room
Alice breaks her blueprint into a secret language of 1s and 0s. This makes the message "clean" and compact, removing any unnecessary noise before she even starts.

Review of Fourier transforms, power spectral density, and linear time-invariant (LTI) systems.
— The book culminates with a chapter that applies all the previous concepts to real-world systems.
Detailed coverage of deterministic and random signals, spectral analysis, probability, and random variables. These chapters provide the essential mathematical foundation needed for signal analysis. Digital Signal Transmission and Analysis
