内容説明
For sophomore/junior-level signals and systems courses in Electrical and Computer Engineering departments.
This text provides a clear, comprehensive presentation of both the theory and applications in signals, systems, and transforms. It presents the mathematical background of signals and systems, including the Fourier transform, the Fourier series, the Laplace transform, the discrete-time and the discrete Fourier transforms, and the z-transform. The contents of each chapter are organized into well-defined units that allow instructors great flexibility in course emphasis. The text integrates MATLAB examples into the presentation of signal and system theory and applications.
