This textbook provides a modern treatment of signals and systems with Fourier, Laplace and z transforms. Intended for an introductory course in the theory of signals and linear systems, it presents the basic concepts and analytical tools in an exceptionally well-written and organized format. Its unique feature is the clearly marked modular structure, which gives the instructor superior flexibility when choosing between sequential coverage and integrated coverage. Chapter outlines highlight specific real-world applications. Supplements Solutions Manual: Available only through your Addison-Wesley Sales Specialist. Matlab M-Files: Available through the Math Works ftp site.
