EU Traffic Noise Causes 10,000 Premature Deaths a Year

2014-12-19 20:24:00| Climate Ark Climate Change & Global Warming Newsfeed

Environment News Service: More than 125 million Europeans could be exposed to levels of road traffic noise above legal guidelines, causing up to 10,000 premature deaths each year, finds a new assessment published today by the European Environment Agency (EEA). "Noise in Europe 2014," the EEA`s first noise assessment report, analyzes exposure to noise levels and the environmental and public health problems that result. The effects of noise are particularly widespread. For the one in four Europeans exposed to noise levels...

Noise Considerations In High Speed Converter Signal Chains

2014-12-18 14:41:25| rfglobalnet Home Page

Designing in high speed analog signal chains can be challenging because there are so many noise sources to consider. In this article, the most common outside noise sources are described, along with how they influence the total dynamic system performance of a high speed signal chain. The article also provides some analog and digital tricks that can be employed to further increase the signal-to-noise ratio in your next design.
