Analog Communication Basics and Amplitude Modulation

Modern wireless and broadcast systems rely on fundamental principles of signal transmission. Understanding how information is mapped onto carrier waves is the essential first step for any aspiring telecommunications or electrical engineer. This course guides you through the foundational math and physics of analog communication, demystifying how signals travel from transmitter to receiver. You will transition from a basic understanding of wave properties to analyzing complex modulated signals, giving you the confidence to discuss, design, and analyze communication links. We also cover modern developments, such as how digital signals interact with analog carriers and the fundamentals of software-defined radio architectures. What you will learn: * Understand foundational signal parameters, frequency domain concepts, and Fourier basics * Analyze the mathematical principles of Amplitude Modulation (AM) and its variants * Compare double-sideband, single-sideband, and vestigial sideband transmission methods * Calculate modulation index, power distribution, and transmission efficiency * Evaluate receiver architectures, superheterodyne tuning, and noise performance * Practice solving standard modulation and demodulation engineering problems This text-only course begins with core definitions of signals, spectrums, and bandwidth before walking you through transmitter and receiver design. You will explore practical mathematical derivations and real-world engineering trade-offs step by step. This course is designed for beginners, engineering students, and hobbyists looking for a solid, math-grounded introduction to communication systems with no prior modulation experience required.
