Signals and systems

The second edition of this comprehensive text continues to explore basic concepts and applications of signal system analysis. It is assumed students have completed a course in circuits and have a proficiency in the use of differential equations. Modern applications are included on such topics as optical system processing and photonics. The text contains abundant examples, illustrations, and problems. Detailed appendixes cover complex variable theory and matrix theory. The second edition features a combined section on optical and acousto-optical principles and applications in signal processing studies. New discussions on the Hartley transform and the discrete Hartley transform have been added where appropriate, and new examples from a variety of disciplines are included. A solutions manual is available to qualified instructors.
