The paper presents a new approach for machine vibration analysis and health monitoring based on blind source
separation (BSS). So, the problem is transferred from the original
space of the measurements to the space of independent sources,
where the reduced number of components is going to simplify
the monitoring problem while the vibration analysis methods
are going to be applied for scalar signals. The assessment of the
approach on a real machine is presented in this paper.
