New edition of a text intended primarily for the undergraduate courses on the subject which are frequently found in electrical engineering curricula but the concepts and techniques it covers are also of fundamental importance in other engineering disciplines. The book is structured to develop in parallel the methods of analysis for continuous-time and discrete-time signals and systems, thus allowing exploration of their similarities and differences. Discussion of applications is emphasized, and numerous worked examples are included. Annotation c. by Book News, Inc., Portland, Or.
