Abstract :
In power spectrum measurement, there are instances in which proportional bandwidth filtering is preferable to constant bandwidth filtering. One such instance is the analysis of sound and vibration from a rotating machine with a varying rotation frequency. The mathematics describing proportional bandwidth filtering are presented.
