This strategy can help detect abnormal increases in certain areas of the spectrum, even when the overall vibration level remains within acceptable limits. By monitoring each band individually, it becomes possible to identify progressive deterioration patterns that would not be visible through a single general alarm.<\/p><p>Moreover, octave bands provide a straightforward structure for configuring alarms in continuous or portable data acquisition systems, without requiring advanced knowledge of spectral analysis.
