>>Suffice to say that in Henry Ott's definitive "Noise Reduction Techniques in Electronic Systems," chapter three's 43 pages on grounding has ABSOLYTELY NOTHING to say about actual earth ground being anything special or that tying your local reference grounds to an actual earth ground will reduce noise in the system.Worse that that, from what I understand adding a separate Earth ground often creates a differential between it and the electrical ground causing, yup, hum.
