What's the Frequency, Kenneth?
Sherlock Ohms 4/22/2013
It was OK when a radio station ran a tad above frequency limits. But when other radio operators in the area used the station's frequency as a base, things could get crazy.
Screws Mess With Filter Design
Sherlock Ohms 4/18/2013
The filter had more rejection at the low end than at the high end since the equivalent capacitance coupling did not provide a transmission at high frequencies.
The Power Factor
Sherlock Ohms 4/16/2013
Post-lunch power surges caused a world of problems at a high-tech defense firm.
The Least-Obvious Signals Sometimes Bite You
Sherlock Ohms 4/15/2013
When is a digital circuit not a digital circuit? When somebody forgot that ultimately everything is an analog circuit, and things like L, R, and C combine in the most insidious ways to derail a design.
Car Radio Fires Up Check Engine Light
Sherlock Ohms 4/12/2013
Apparently the 2003 Saturn Vue has some interconnections between sensors that depend upon the integrity of the radio ground strap for proper operation of the engine and transmission control computers.
Chip Suppliers Target Vehicle Complexity
Electronics News 4/2/2013
Chip makers are hoping a new breed of microcontrollers will begin laying the foundation for a solution to one of the auto industry’s most vexing design problems -- electronic complexity.
My Opinion on Testing Without ATS
Automated test software, or ATS, is nothing new. But as systems grow in complexity, the need for automated testing, and likewise automated testing software, grows correspondingly.
The National Aeronautics and Space Administration’s recently announced plan to put an electric airplane in the air by 2018 is forward-looking, but hardly unique.
Engineers can channel the eye of the tiger and rise to the challenge, with a number of prize or award-giving contests out there to test your metal and intellectual prowess.
