Cover Story 
Designing an accessible board
By Ron Wilson, Executive Editor, EDN
Design in access to verification and debugging during—not after—the development of a board-level product.
 
Design Feature 
Comparing comparators: Measure signals, get results
By Paul Rako, Technical Editor, EDN
Simple in concept, voltage comparators have myriad specifications that complicate their application.
Deep packet inspection optimizes mobile applications
By Mike Coward, Continuous Computing
Mobile data provides a notable growth opportunity for cellular operators, but adoption will be slow unless networks can provide good service to all subscribers. Deep packet inspection enables operators to understand the applications their subscribers are using and to build appropriate networks.
