While delivering power, your AC tap also delivers a significant amount of line noise. The reasons include, switching power supplies and the harmonics they backfeed into our AC power mains, the deterioration of our power grid from age and use, and the noise pollution generated from the massive amounts of electronic devices on our grid at any given time.
This output from real-time noise analysis software shows the noise attenuation curve of a standard AC noise filter. Note the uneven shape of the curve (the green line).
This output is the same analysis except that it is using Furman’s Linear Filtration Technology. The noise attenuation curve is smooth and linear, without the resonant peaking seen in the standard filter.
