Focusing on the foundational concepts of abstraction, this textbook offers a comprehensive introduction to Signals and Systems, suitable for both classroom use and self-study. It covers essential functions for signal analysis and delves into linear time-invariant systems, supported by Fourier series and transforms. Practical applications like sampling and modulation are explored, alongside advanced tools such as the Laplace and Z transforms for system analysis. Key topics include system stability and feedback, providing a thorough understanding of these critical concepts.
