Ground loops are a common yet often overlooked issue in building electrical systems. While they may seem minor during design or construction, ground loops can significantly impact system performance ...

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 ...

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 ...

With a little guidance on ground-source heat pump design temperatures and a few rules of thumb for ground loop flow rates, most engineers are pretty comfortable designing the building side of a ground ...

If you have connected your computer to your home entertainment system and heard a speaker hum, you may need to get rid of background interference caused by differences in electrical resistance between ...
