As a final remark, the above insights and conclusions indicate that the Hilbert-transform based con- version of raw data to an analytical signal is an advantageous additional robust and straight forward pre- processing step to advance beyond the classical POD method.	cache/ispiv-113.pdf	txt/ispiv-113.txt
