Signals & systems, 2nd edition

Signals and Systems is a foundational textbook for undergraduate courses in electrical engineering and related fields. The book develops methods for analyzing both continuous-time and discrete-time signals and systems in a parallel manner, highlighting their similarities and differences. The content of a typical "Signals and Systems" textbook includes: Fundamental Concepts: Definitions of signals and systems, and their basic properties like linearity, time-invariance, causality, and stability. Time-Domain Analysis: Exploration of system behavior using methods such as the convolution sum and convolution integral. Frequency-Domain Analysis: Detailed coverage of Fourier series and Fourier transforms to understand signals in the frequency domain. Advanced Transforms: Introduction to the Laplace transform for continuous-time systems and the Z-transform for discrete-time systems. Applications: The book emphasizes practical applications of these concepts in areas such as filtering, communication, and sampling. Many editions also include exercises and examples using software like MATLAB to reinforce learning and provide hands-on experience. The text is designed to be accessible to beginners with no prior experience in system analysis, convolution, or Fourier analysis.
