Abstract :
This paper represents the first phase of an ongoing investigation into the nature of sinusoidal types of random processes associated with real world phenomena. Some noteworthy results include the normality of amplitude and frequency, characterization of the same as stationary random processes, and potential to improve condition monitoring of rotating machinery
