Bit statistic
The bit statistic function visualizes the state of all bits in the digital
audio signal.
The display allows you to see quickly which bits of the audio data are
permanently low (0), high (1) or changing (indicated via the up/down
arrow symbol).
Actual word length: The actually measured resolution is
displayed.
vuCp data: The following bit information is displayed:
• V, validity bit indicating whether the digital audio bits may
be converted to an analog audio signal; if the validity bit is
permanently 0, the incoming data is valid.
• U, user bit containing any user bit information.
• C, status bit containing the channel status information, this bit
is normally changing.
• P, parity bit, plausibility check of actual subframe, this bit is
normally changing.
Auxiliary bits: These bits may be used for
• Audio data
• 2 nd channel, e.g. talk back
