Streamlining Digital Signal Processing or Security Awareness

Streamlining Digital Signal Processing: A Tricks of the Trade Guidebook

Author: Richard G Lyons

This book is more than just a compilation of the original articles. All of the material in the book has gone through careful editorial review and has also benefited from the feedback of the readers of the magazine; the result is a consistent across all of the articles. Additionally, the authors have used this opportunity to include the additional explanations, applications, and illustrations that could not be included in the original articles due to space limitations.
