ABSTRACT:
A system and method for monitoring a condition and an operation of a periodically moving object is provided. Herein a synchronized time average is calculated for a measurement signal, the signal containing periodical variations and obtained from the object response. In general, a frequency response is determined based on the periodical variations of the measurement signal. A signal component representing the determined frequency response is filtered from the measurement signal. The filtered signal is used as a synchronizing signal. A synchronized time average of sequences, determined by dividing the measurement signal by the synchronizing signal, is calculated.
