Multiphase boost converter eases 12V battery 'cranking deep' Design How-To 4/29/2011 4 comments Auto start-stop systems offer improved fuel efficiency and emissions, but vehicle electronics need to be protected from cranking transients. A multiphase boost converter is ideal for this function and can also simplify supplying power audio components in the infotainment system as well as isolating regenerative braking energy storage.
Yokogawa DL850 ScopeCorder Product News 4/28/2011 Post a comment A new real-time mathematics option for the Yokogawa DL850 ScopeCorder introduces many new DSP-based functions that boost the instrument's power analysis capabilities as well as adding features such as sensor linearization and electrical to mechanical conversion.
Loudspeakers: Objective evaluations - Part 6: Other measurements Design How-To 4/27/2011 3 comments In the sixth and final excerpt from the book "Sound Reproduction: The Acoustics and Psychoacoustics of Loudspeakers and Rooms," Floyd Toole considers other factors affecting loudspeaker performance beyond frequency response, including phase response, impedance, wire, damping factor and sensitivity.
The six basic audio tests in video tutorials Test & Measurement Designline Blogs 4/27/2011 3 comments A series of video tutorials on "the six basic audio measurements" - produced by audio test company Audio Precision - covers the topics of frequency response, THD+N, phase, SNR, crosstalk and level & gain.
ESD measurements enhance simulations Design How-To 4/26/2011 Post a comment Researchers at the Missouri University of Science and Technology’s EMC lab study the effects of ESD and develop models that designers can use to predict the performance of the protection they add to electronic circuits.
Tools spur ECU CAN/LIN communications Design How-To 4/22/2011 Post a comment With the increasing use of in-vehicle networks, the development of automotive electronic control units must not only consider the software requirement, but also the implementation of the embedded software via a data bus such as CAN or LIN.
Power Line Communication integrates electric vehicles with the Smart Grid Design How-To 4/15/2011 6 comments A compatible charging infrastructure and communication between an EV and any potential "charging spot" is required for easy and practical use. The established Power Line Communication (PLC) standard in the Smart Power Grid offers a robust and long term available setup—and the prospect of grid stabilization (charging back to the grid).
Gearing Up for parametric test’s high voltage future Design How-To 4/12/2011 Post a comment Many parametric test engineers are learning to cope with new high voltage process requirements. Not surprisingly, high voltage processes require high voltage parametric testing for process control and reliability monitoring. Part of the challenge lies in the fact that these new high voltage requirements add to the list of parametric tests rather than replacing some portion of it.
Why it pays to test before you fly Product How-To 4/5/2011 Post a comment In a recent interview with T&M World's contributing editor Larry Maloney, John Monahan president of RT Logic described his companies communications-test and signal-monitoring technologies.
Do parts from Japan pose radiation risk? News & Analysis 4/1/2011 15 comments Questions have arisen about contamination and radiation levels of electronics parts from Japan, though no dangerous radiation levels have been detected in any cargo, according to a trade group.
