NASA Finds Cause of Voyager 2 Glitch

astroengine writes "Earlier this month, engineers suspended Voyager 2's science measurements because of an unexpected problem in its communications stream. A glitch in the flight data system, which formats information for radioing to Earth, was believed to be the problem. Now NASA has found the cause of the issue: it was a single memory bit that had erroneously flipped from a 0 to a 1. The cause of the error is yet to be understood, but NASA plans to reset Voyager's memory tomorrow, clearing the error."

  22. Re:Analogue amplification gives even harmonics by Culture20 · · Score: 2, Funny

    Analogue amplification gives even harmonics whereas digital amplification gives odd harmonics. And even harmonics are more pleasing to the ear. You can obviate the problem of odd harmonics by producing more harmonics to nudge the signal back to more pleasing shapes, but that means that an op-amp running at 192kHz can produce a pseudo-analogue amplified signal equating to an analogue amplifier with a ceiling of 30kHz.

    It's one reason why early CDs were, frankly, crap: the sound engineers used the same techniques making the sound track for the CD that they did for the analogue LP. But the CD has different strengths and weaknesses and some processes that utilised the strength of LP and avoided the weakness of them were unsuited to the CD characteristics.

    AFAIR, the re-release of the White Album was the first one where they went back to the original tapes and worked the signal to accord with the CD and digital amplification strengths.

    Now they're ditching the high dynamic range of CD in the loudness war.

    Way to go, guys.
