    Abstract

    In this paper random sampling was tested as a sampling method in order to reduce data of bearing measurements. Spectrums of random sampled vibration and acoustic emission measurements were defined with an iterative algorithm. A wireless measurement system was constructed and measurements were carried out in a laboratory. Results showed that random sampling is a potential data reduction method for wireless data transfer of bearing measurements. Especially random sampling of acoustic emission signals is attractive because acoustic emission waves are measured at high frequencies.
