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 ...

Microcontroller applications often have low-level sensor signals and moderate power-drive circuitry, in addition to the microcontrollers. A peaceful coexistence with these three extremes requires a ...

Integrating digital and mixed-signal IP blocks in SoCs poses a considerable challenge to verification of power/ground and substrate noise. Traditional methods of power supply noise analysis are unable ...

Unwanted noise is introduced in all electronic circuits and providing sufficient noise margin for Vcc and GND specifications is paramount, writes Howard Venning Unwanted noise is introduced in all ...

The insertion of unwanted noise into the ground line by the filters in a power supply. See ground loop and inter-system ground noise. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction ...

Digital transition switching is the primary cause of noise in mixed-signal devices. Signal noise and immunity to power, ground, and substrate noise all benefit from using differential circuits. Design ...

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 ...

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 ...

Boeing and General Electric expect to meet noise reduction targets for the 747-8’s GEnx-2B engine after completing a three-week ground test on a GE90-115B powerplant. “The test results, combined with ...

You've just connected your system and there's a buzz or hum that won't go away. You're running your gear through power conditioners and you're beating your head against the wall trying to figure out ...
