Cover Story
- Safety check: Wireless sensors eye tire pressure
Tire-pressure monitoring is one of the biggest safety improvements that electronics technology can give drivers. Direct-pressure-measurement systems have now set the stage to displace alternative approaches. - FROM EDN EUROPE: Ethernet keeps pumping the data
It's hard to imagine a technology that can almost seamlessly embrace a three-order-of-magnitude bandwidth increase using copper wiring that was originally designed for voice services. This first article of a two-part series describes how Ethernet today, as 20 years ago, continues to amaze.
Design Features
- EDN hands-on project: Offshore outsourcing: now boarding
A trip to China may just be the ticket to take your design to reality. - Spectral content of NRZ test patterns
NRZ-test-pattern properties, such as data rate and pattern length, determine important time- and frequency-domain characteristics. - Digital common-mode noise: coupling mechanisms and transfers in the z axis
Digital noise can couple into sensitive circuit regions of an analog/digital board. The process of noise production from the common-mode point of view in the z axis merits careful analysis. - Rework within your reach
A low-cost rework method safely and effectively removes and replaces modern "hidden-lead" surface-mount packages.
