@ptss Einstein theorized that such noise existed but assumed it was not measurable. Johnson showed that it was and Nyquist explained why. So both names are associated with noise from resistors. Do you know which ground connection is being filtered in this case? If we are talking about the 3rd wire of an AC outlet (the ground connection) I find myself skeptical. This is because a properly designed bit of audio gear should put no noise into the safety ground- although that word 'should' is there telling you this does not happen all the time! Other things unrelated to audio might put noise in that ground. But you might want to keep in mind that putting any kind of impedance in series with the safety ground could lead to Bad Things- like a shock hazard, as the difference in potential between the equipment and the basement floor could be enough to create a shock hazard. Its on this account that I don't do anything that might mess with the purpose of the safety ground. |
