Transmitting data over long distances is fraught with potential problems. A ground loop can be a source of interference that can induce a noise voltage between the grounds on either end of the ...

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 ...

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 ...

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 ...

Machines automated with electric actuators and drives are flexible, powerful, and easy to use. But such machines often operate in harsh factory conditions subject to electrical noise. This noise is ...

Successful shield grounding cannot be divorced from the issue of good signal grounding; they go hand-in-hand. Thus both subjects will be treated as a combined topic in Part 2 of this series.

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 ...

Ground loops are the topic this weekend at a seminar in DC. The Society for Motion Picture and Television Engineers is having a joint meeting with AES-DC. “Understanding, Finding and Eliminating ...
