The journey begins here. This foundational chapter answers the most basic yet critical questions: What is communication? It covers the need for modulation and frequency translation 。 It defines the essential building blocks of a communication system, including the transmitter, receiver, and the concepts of multiplexing (FDM and TDM).
Every communication channel introduces random, unwanted electrical signals known as noise. Analyzing how noise degrades a signal is critical for designing reliable systems.
