I glanced at a few articles about this. They're about noise due primarily to thermal fluctuations in the diode, which apparently in many cases is lower than the shot noise (shot noise is noise due to the fact that the electric current is made up of a finite number of electrons). This is an incredibly tiny effect, and not only that will occur in EVERY circuit component, not just LEDs - every resister, capacitor, wire, etc. It's measurable with very sensitive equipment when the currents involved are extremely small. Note I'm talking about steady state LED noise - if the thing is flickering on and off, that might induce some more significant noise. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=23227 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
