Principles of Analog Communications

Analog communication forms the backbone of modern telecommunications, from radio broadcasting to foundational signal processing. Understanding how signals are modulated, transmitted, and received is essential for anyone entering the field of electrical and communication engineering. This text-based course guides you from absolute beginner to a confident grasp of analog communication systems. You will learn the core mathematical and physical principles behind signal transmission, enabling you to analyze and design basic communication circuits. What you'll learn: Understand foundational signal theory, frequency domains, and basic communication models; Analyze Amplitude Modulation (AM) and Frequency Modulation (FM) techniques and mathematical derivations; Explore the architecture of superheterodyne radio receivers and transmitters; Evaluate noise performance and signal-to-noise ratio (SNR) in analog systems; Connect classical analog concepts to modern technologies like Software-Defined Radio (SDR). You will start with key terminology and foundational definitions of signals and spectra before moving into detailed derivations of modulation techniques. The course concludes with practical problem-solving exercises that reinforce real-world application. This course is designed for beginners, engineering students, and tech enthusiasts with no prior experience in communication systems.
