through monitoring. Vibration data is processed to determine the condition of components in the drivetrain. One of the most powerful algorithmic tools for vibration analysis is the time synchronous average (TSA). Time synchronous average resamples the vibration data synchronously with a shaft, and is the basis of numerous gear and shaft condition
