WebJul 26, 2015 · Synchronous averaging (i.e., “complex averaging,” “time domain averaging,” or “vector averaging”) is a technique originally developed to analyze the vibration signature or rotating machines and gearboxes. It can be used to improve the S/N ratio measurement. This article was published originally in Voice Coil November 2012. WebWith time synchronous averaging, only harmonic peaks exist in the spectrum and non-harmonic peaks are averaged out. Conclusion TSA is an alternative to spectrum based averaging that is useful for some applications especially gear vibration analysis. The averaging is performed in the time domain instead of the usually frequency domain. It is …
