All bandwidth frequencies are present in each burst but may not be complete cycles as block period is truncated. Two bursts being identical (respectively fixed or random phase) they are 100% correlated. Two burst random from two separate generators will not be correlated signals. | All bandwidth frequencies are present in each burst but may not be complete cycles as block period is truncated.

Back to the roots of vibration analysis: Everybody knows that our ears and brain is the best instrument to feel and interpret vibration signals. This is also why we take so much care in removing these NVH signals from our machines, vehicles and appliances. The audio playback of vibration (or any other) signal allows the user to "listen in" on what your OROS analyzer is "hearing". | Back to the roots of vibration analysis: Everybody knows that our ears and brain is the best instrument to feel and interpret vibration signals.

===Player : play any signal on output | ====Play-Back on PC speaker==== | ||
If you need to listen a signal already record, do not used output channel. We advice to use the playback on PC speaker define here: | |||
From any of the previous configurations, the recorded signal could be listened on the PC loud speakers. | |||
