Research and Markets: The Book 'Discrete-Signal Analysis and Design' Includes a Valuable, Full-Featured Student Version of Mathcad 14.0

DUBLIN, Ireland—(BUSINESS WIRE)—January 21, 2008— Research and Markets ( has announced the addition of Discrete-Signal Analysis and Design to their offering.

This introduction to discrete-signal analysis & design provides a step-by-step approach that allows electrical engineers to go beyond the traditional continuous-signal pencil and paper analysis and design.

Specifically designed for easy individual at-home study as well as for classroom learning, the book requires only undergraduate level mathematics for understanding. The style of the book is conversational, with occasional re-examination and reinforcement of especially important basic concepts; throughout, the author includes complete self-study examples using full-page Mathcad Worksheets.

The book includes a valuable, full-featured student version of Mathcad 14.0 which offers a sophisticated math tool for a wide range of applied mathematics capabilities. The software will remain useful long after readers have mastered the text.
