Each week, the editor of Planet Analog finds items of interest and then features them in two sections, entitled “Also of Interest” and “Elementals”. Each cites items from publications outside the Planet Analog and EETimes portfolios. And we have a new feature: an archive of recent weekly Planet Analog Newsletter editions, as pdf files, see the list at the very bottom.
“Also of Interest” and “Elementals” is an extension of our belief that engineers are interested in on-going tutorial on obviously relevant topics, as well as the serendipity of exploring topics which are not directly related to their jobs, but which will broaden their knowledge and sometimes spurs innovative and creative approaches. The first box highlights a items of general interest to the engineer, while the second highlights basic and tutorial electronic-engineering material.
Among the publications we check are IEEE Spectrum , Machine Design , Design News , Laser Focus World , EDN , Electronic Design , NASA Tech Briefs , Portable Design , and Physics Today , plus others.
Consider these items as “online-only” extras, and worth a look. (Please note: there are also links to the previous weeks' editions, below this week's items.)
Also of Interest:
- Simple, highly effective fixtures entail minimal modification:
“Reducing Unsteady Loads on a Piggyback Miniature Submarine,”
NASA Tech Briefs , February 2009 - A popular instrument created less than ten years ago has inspired musicians and scientists alike to explore its sound properties:
“The extraordinary sound of the hang,”
Physics Today , March 2009 - Old LPs can sound as good as new–even when cracked in half, using this laser-based turntable:
“Give Your Records a Break,”
IEEE Spectrum , March 2009 - Two examples at opposite ends of the spectrum explore fluid-flow pressure drops:
“Solving Fluid Pressure Drop in Complex Mechanical Assemblies,”
Desktop Engineering , February 2009 - Want to swim with the fishes? Try this swimmable submarine:
“The Exosuit Diving Suit Stays Flexible Underwater,”
Machine Design , February 19, 2009
Elementals:
- Rather than use the simple rule of thumb of including the 5th harmonic, we should use rise/fall time to detemine the bandwidth required to measure a high-speed digital signal:
“Is the 5th Harmonic Still Useful for Predicting Data Signal Bandwidth?,”
High Frequency Electronics , January 2009 - Embracing DDR3 memory means higher performance, lower power, and simpler board design, but at the cost of interface complexity:
“Step Up To DDR3 Memory,”
Electronic Design , January 29, 2009 - Description of a basic test instrumentation setup and calibration procedure used for noise parameter measurement:
“Understanding Noise Parameter Measurement,”
Microwave Journal , February 2009 - Understanding phase noise in oscillators and synthesizers makes it easier when comparing the performance of different sources at different frequencies:
“Know the Nuances Of SSB Phase Noise,”
Microwaves & RF , February 2009
