Writing Better Requirements
Author: Ian F Alexander
Experience has shown us that investment in the requirements process saves time, money, and effort. Yet, development efforts consistently charge ahead without investing sufficiently in the requirements process. We are so intent to develop the technical solutions that we are unwilling to take the time and effort to understand and meet the real customer needs.
--From the Foreword by Ralph R. Young, author of Effective Requirements Practices
If you are involved in the systems engineering process, in any company -- from transport and telecommunications, to aerospace and software -- you will learn how to write down requirements to guarantee you get the systems YOU need.
What skills will I learn?- How to write simple, clear requirements -- so you get what you want
- How to organize requirements as scenarios -- so everyone understands what you want
- How to review requirements -- so you ask for the right things

Principles of Digital Audio
Author: Ken C Pohlmann
THE #1 BEST-SELLING BOOK ON DIGITAL AUDIO ENGINEERING
This definitive text provides comprehensive coverage of today’s leading digital audio technologies as well as a thorough survey of fundamentals and theory. Written by well-known audio engineering expert and best-selling author Ken Pohlmann, four previous editions have been valued for their clear explanations and have been widely used as college texts and professional references. The fifth edition of Principles of Digital Audio has been extensively updated and revised to reflect ongoing widespread changes in the audio industry.
Beginning with an in-depth discussion of digital audio recording and reproduction, the text then details perceptual low bit-rate coding, CD and DVD disc formats, digital audio broadcasting, internet and network audio, and DSP. From the basic theory to the latest technological advancements, Principles of Digital Audio completely covers this multifaceted field, including topics such as:
- MP3, AAC, and Dolby Digital audio coding
- DVD playback and recording formats
- PC-based desktop audio systems
- 5.1-channel surround-sound coding
- HD Radio and satellite radio
- Music downloading and streaming
- Digital signal processing
