Description

Using everyday examples and simple diagrams, two leading DSP consultants and instructors completely demystify signal processing with this text. Students will discover what digital signals are, how they’re generated, and how they’re changing life. Students will learn all they need to know about digital signal collection, filtering, analysis, and more, and how DSP works in today’s most exciting devices and applications.

Features

  • Plain-English explanations of digital signal collection, filtering, analysis, and modern applications
  • Includes a complete glossary demystifying signal processing jargon and acronyms
  • By Richard Lyons, internationally-renowned author of Prentice Hall's best-selling Understanding Digital Signal Processing, Third Edition
  • An indispensable resource for all marketers, technical writers, PR specialists, and non-technical managers and investors concerned with DSP technology and products
