EMC Basics #5: I/O as critical circuits article gives some useful tips on the EMC issues related to inputs and outputs. Digital inputs/outputs — The key concern for digital interfaces is ESD. A secondary concern is radiated emissions. Radiated susceptibility is rare with digital I/O, although possible at very high RF levels. The solutions for →
The idea if replacing fluorescent light bulbs with LEDs seems to become popular. There are different kind of products made for that purpose, some are good and some not so good. So I felt it was now good time to test this technology. LED technology promises to reduce power consumption about 50% of fluorescent bulbs →
