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 ...

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 ...

If you have connected your computer to your home entertainment system and heard a speaker hum, you may need to get rid of background interference caused by differences in electrical resistance between ...

The Model 4999 low-pass filter signal conditioner furnishes individual input ground isolation on each input channel to eliminate the group loops often encountered with multiple-channel measurements.

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 ...
