Gabor Transform-Based Order
Tracking
This chapter discusses a new order analysis method based on the Gabor
transform and provided by the LabVIEW Order Analysis Toolset that
enables you to complete the following tasks:
•
Analyze the order components of a noise or vibration signal
•
Reconstruct the desired order components in the time domain
Overview of Gabor Order Analysis
The Gabor transform can give the power distribution of the original signal
as the function of both time and frequency. Figure 3-1 shows a
frequency-time spectral map computed by performing a Gabor transform
on a sample vibration signal from a rotating machine.
