Having problems with your process controls and electrical instrumentation? The source may be a grounding disturbance known as a ground loop. According to the ANSI/ IEEE Standard Dictionary of ...

These magical creatures crop up out of nowhere and fry your electronics or annoy your ear holes. Understanding them will doubtless save you money and hassle. The ground loop in a nutshell is what ...

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 ...

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 ...

The ultimate goal of sound and image reproduction is realism — the kind that creates suspension of disbelief in the listener or viewer. And nothing breaks the spell like background buzz during a quiet ...

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 ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...

As on-board processing becomes more sophisticated integrating K-band RF, GSPS ADCs/DACs, and GHz-speed FPGAs on a single PCB, questions often arise about satellite grounding, particularly mixed-signal ...

I'm trying to figure out a way to deal with a ground loop problem I have at home, this is 60hz mains hum that comes out of speakers, even when nothing is connected to the device besides power cable. I ...

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 ...
