Analog Communication Systems: Core Principles and Applications

Analog communication forms the backbone of modern signal processing and telecommunications engineering. Understanding how continuous signals are modulated, transmitted, and received is essential for anyone entering the electronics and communication field. This comprehensive text-based course guides you from the fundamental mathematics of signals to practical transmitter and receiver architectures. You will gain a clear, conceptual understanding of how information is carried over physical mediums and learn how to analyze system performance under noisy conditions. What you'll learn: Understand foundational signal properties, Fourier transforms, and spectral analysis; Analyze amplitude modulation (AM) and angle modulation (FM/PM) techniques; Evaluate transmitter and receiver designs, including superheterodyne architectures; Calculate noise performance, signal-to-noise ratios, and figure of merit; Explore modern applications of analog concepts in software-defined radio basics; Practice solving core engineering problems through clear, step-by-step written exercises. The course starts with basic definitions of signals and systems before moving systematically through modulation types, mathematical derivations, noise analysis, and practical receiver designs. Designed for beginners and engineering students looking for a clear, written guide to analog communication, this course requires no advanced prerequisites.
