WebTime-synchronous averaging averages out zero-mean random noise and any waveforms not associated with frequencies of the particular shaft. This makes the process of fault detection easier. Use the function tsa to generate time-synchronized waveforms for both the pinion and the gear. Specify time-synchronized pulses for the pinion.

WebA short description and working of Time Synchronous Averaging Filters WebTime domain synchronous average (TSA) and moving average (MA) are the most commonly used average techniques in engineering. TSA has the advantage at periodic signal detection by depressing noises and asynchronous signal components. MA is effective to remove noises while keeping signal periodicity.
