A circular path created between the data lines and the ground wires when electronic devices communicate with each other. When systems have earth grounds through different power sources, differences in ...

All Code references are based on the 2005 NEC. The grounding and bonding requirements in this column apply to solidly grounded systems that operate at not more than 600V, including 120/240V, 120/208V, ...

Unwanted disturbances in the data lines between two electronic devices communicating with each other due to unbalanced reference voltages in the ground loop. Data signals can be altered, and ...

In this final installment of a series of articles aimed at helping broadcasters protect their installations from powerline and lightning-induced surges, we focus on the importance of electrical ...

As semiconductor device performance increases, especially for low power and higher speed ICs, testing low frequency 1/f, RTN and phase noise with improved signal-to-noise ratio is required. Finding ...

Has anyone had any experience using HDMI fiber optic converters/extenders? I have a weird ground loop problem in my system which I traced back to my HTPC. I get hum whenever I join the grounds between ...

Grounding of electrical systems is an often forgotten yet important design consideration. Issues with proper grounding can be complicated, confusing, and downright frustrating to solve. So much so ...

As shown in Figure 1, this issue had been previously addressed during pre-internet times in EDN of January 18, 1990 but a further detailed look at the idea is warranted thirty-four years later. Figure ...
