Signals And Systems: An Introduction (2nd Edition)

This book integrates and simplifies all the concepts professionals need to understand signals and systems.The book introduces basic concepts, including the representation and properties of signals in the time domain. It introduces systems from the viewpoint of signal transformations, leading to a description of differential and difference equations. It introduces convolution, frequency response, periodic and aperiodic signals, Fourier, Laplace and Z transforms. Once transforms are understood, the book introduces the system transfer function and calculation of system response. This edition includes new chapters on random signals and spectral analysis.All engineers, researchers and students concerned with signal processing.
