For a warmer, more natural sound, this monophonic synthesizer (http://rbi.ims.ca/4928-541) uses two analog, as well as two digital oscillators. To interface the digital part to the analog, designer Dave Smith chose Analog Devices' AD1836A (http://rbi.ims.ca/4928-542), a multichannel 24-bit, 96 kHz codec. The codec has two stereo Analog- to-Digital Converters (ADC) and three stereo Digital-to-Analog converters. The ADCs operate with -92 dB total harmonic distortion (THD) + N and 105 dB signal to noise ratio (SNR) and dynamic range. The DACs have 95 dB THD + N and 108 dB SNR and dynamic range.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
