Signals and Systems: Core Principles and Problem Solving

Signals and Systems is the fundamental mathematical framework underpinning electrical, communication, and digital processing engineering. Learn the essential concepts required to understand how signals are generated, manipulated, and transmitted. By the end of this course, you will be able to classify, analyze, and manipulate signals and systems using powerful tools like the Fourier, Laplace, and Z-transforms, preparing you for advanced engineering studies and application. What you'll learn: * Understand the classifications of signals and systems (e.g., LTI, causal, stable) and their defining properties. * Master continuous and discrete-time convolution for determining system output responses. * Apply the Continuous-Time Fourier Transform (CTFT) and Discrete-Time Fourier Transform (DTFT) for frequency domain analysis. * Analyze stability and causality using the Laplace and Z-transforms, including region of convergence (ROC) concepts. * Practice applying the sampling theorem and recognizing the effects of aliasing in digital signal processing. This course begins with foundational definitions and system properties, moves through time-domain analysis using convolution, and culminates in comprehensive frequency-domain analysis using various transforms. The material is reinforced through clear written explanations and focused problem sets to ensure mastery of every concept. This course is designed for absolute beginners in engineering who need a solid foundation in Signals and Systems. No prior knowledge beyond basic calculus is required.
