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 ...

There is one class of signals we have not yet covered, and that is those signals which pass within the unit from one board to another. Typically these are digital control signals or analog levels ...

Ground start is the primary analog signaling method used between telephone switches such as the central office (CO) and a private branch exchange (PBX). It offers a way to indicate on-hook and ...

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 ...

A signal-injection circuit for control-loop analysis is flat from dc to 200 kHz, isolated from chassis ground and easily constructed with a readily available instrumentation amplifier Brian Keeney, ...

The 4- to 20-mA current loop is ubiquitous in the world of controls in manufacturing plants. Discrete logic, microprocessors, and microcontrollers easily cover the digital portions of control schemes, ...

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 ...
