A “worst case” analysis of rail voltage decoupling for a digital circuit board was required, but the challenge was to determine what the worst case current pulse circumstances could actually be. The ...

East Japan Railway Co. (JR East) announced on Sept. 26 that metal shavings left during the manufacturing process may have triggered a switch and caused the recent decoupling of a Shinkansen while in ...

I love near field probes because they let me “see” magnetic and electric fields with an oscilloscope or with a spectrum analyzer. They let locate sources of emissions in board, cables, and systems.

If you’ve been building circuits for any length of time, you probably know you need decoupling capacitors to keep your circuits stable. But even though it’s a favorite technique of ours, just ...
