Signals and Systems Fundamentals: Part 1

Analyzing and processing signals is at the heart of modern electrical, communications, and systems engineering. To build a solid foundation, you must first master the mathematical core of how signals and systems behave and interact. This text-based course guides you step-by-step from foundational definitions to advanced analysis, preparing you to solve complex engineering problems with confidence. You will learn how to classify signals, evaluate system properties, and apply algebraic shortcuts to simplify difficult analytical challenges. What you'll learn: Understand core signal classifications including continuous-time, discrete-time, periodic, and energy signals; Determine system properties such as linearity, time-invariance, causality, and stability; Apply mathematical transformations to independent variables like time-shifting and scaling; Solve analytical engineering problems using proven shortcut methods and structured steps; Practice with foundational exam-style questions to test your comprehension of core concepts. The course begins with essential terminology, basic definitions, and signal classifications, before moving into the mathematical properties of systems and practical problem-solving techniques. This course is designed specifically for beginners, engineering students, and self-directed learners with no prior background in signal processing. Start building your engineering foundation today.
