Local spec takes its mark News & Analysis 8/4/2008 Post a comment For some observers, the performance of the athletes next month will take a backseat to the performance of China's much-anticipated, homegrown 3G wireless network. The time-division, synchronous code-division multiple-access (TD-SCDMA) 3G network began commercial trial rollouts in earnest on April 1. It is scheduled to cover at least 10 Chinese cities in time for the Games, Aug. 8-24
Sun shines on the green engineer News & Analysis 8/4/2008 Post a comment The buzz at a recent solar technology conference was palpable. Engineers stood on long lines waiting to get into technical sessions and, once seated, stayed until the last question was answered.
Olympics technology: LEDs brighten the venues News & Analysis 8/4/2008 Post a comment Contractors for the Beijing Olympics considered fluorescent lighting for some of their key venues until they evaluated light-emitting diodes and found them to be a more colorful, lower-power route to illuminating their creations.
Torch is passed to MEMS News & Analysis 8/4/2008 Post a comment Microelectromechanical system (MEMS) chips have been built into the Olympic Torch--not the one that traveled around the world, but the replicas that spectators will wave at the 2008 Beijing Summer Olympics.
Ideal diode controller suits low voltage applications Product News 8/1/2008 Post a comment Low voltage applications where a slow handoff by controllers can result in a voltage droop during supply switchover could benefit from Linear Technology's LTC4352, a 0V to 18V ideal diode controller that smoothes current transfer between supplies in diode-OR applications.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
