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 ...

Kramer Electronics has introduced four isolation transformer models — the TR-1, TR-1A, TR-2A and TR-3 — that eliminate noise in AV signals caused by ground loop problems. In many video and audio ...

I can't seem to get my CATV feed grounded well enough to prevent ground loop noise on the audio and video from my PC (which is in another room). I grabbed the el-cheapo Radio Shack audio ground loop ...

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 ...

How optical isolation works. Source: B&B Electronics. Some of you may know that I moonlight as the guitar player in a hard-edged blues/rock band. Playing at the various clubs around town, I run into ...

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 ...
