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 ...

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 ...

So in my car I think i have a ground loop problem, but im not positive. Its sort of a cyclical noise, so its quiet, then buzzes, quiet, then buzzes, etc. Its not terribly bad, I really dont notice it ...

To maximize the quality of your audio when you’re producing a live event, it’s important to assess your signal carefully all the way through the chain, as I discussed in my May/June 2015 article How ...

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 ...

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 ...

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 ...

Your new plasma HDTV is beautifully hung on the wall. The cables are run behind the drywall and under the floor to an equipment rack built into an unused closet space. The speakers are a recessed bit ...
