Abstract
Since the variations of rotational speeds can provide significant information in diagnosing a rotating machine. Substantial effort has been expended in attempts to find the detailed variations of speeds. Speed variations have been estimated with varying degrees of success. A portion of the effort has been motivated by active research and development of monitoring systems for turbines and oil-drilling rods. The viability to accurately estimate small variations using noise contaminated records can be done by constructing a modified digital demodulation scheme.
