Possible Analytical Methods for Condition-Based Monitoring
The analysis of machine states in CBM can be accomplished using various methods. The probably most common methods are analysis in the time domain, analysis in the frequency domain, and a mix of the two. This tip reviews high level methods for using each of these approaches to determining machine health.
