Fig. 4-12 Example for level measurements at various peak excursion settings
Maximum relative level change of the measured signals:
Signal 2: 42dB
Signal 3 30dB
Signal 4: 46dB
With Peak Excursion 40dB signals 2 and 4 are detected by NEXT PEAK or
NEXT PEAK RIGHT. Signal 3 is not detected since it is only decreased by 30
dB before rising again.
Order in which signals are found:
PEAK: Signal 1 or PEAK: Signal 1
NEXT PEAK: Signal 2 NEXT PEAK RIGHT: Signal 2
NEXT PEAK: Signal 4 NEXT PEAK RIGHT: Signal 4
With Peak Excursion 20dB signal 3 is detected as well since its highest level
change of 30 dB is now higher than the peak excursion.
Order in which signals are found:
PEAK: Signal 1 or PEAK: Signal 1
NEXT PEAK: Signal 2 NEXT PEAK RIGHT: Signal 2
NEXT PEAK: Signal 4 NEXT PEAK RIGHT: Signal 3
NEXT PEAK: Signal 3 NEXT PEAK RIGHT: Signal 4
