Envelope Detection for Machine Vibration

[preston_johnson]

During the recent Vibration Institute Meeting, there was several discussions regarding envelope detection and tracking. I posed this request to our LabVIEW Order Analysis Toolset developers and this is the implemenation they suggested, it uses the Hilbert Transform found in the LabVIEW Full Development System. Its input is a filtered order, band pass, which the order tracking function provides.

I am very interested in your feedback on this example, and any other suggestions anyone might have.

Looks good, although I'm not sure why the sequence frames are there.
