Synchronous Average

Synchronous Average

Obtaining an accurate measurement of a rotational signal in the presence of complex systems, other rotating signals, and strong structural responses can be very challenging. The signal may be very noisy and inaccurate or even impossible to decipher. These measurement situations benefit greatly from synchronous averaging.

The synchronous averaging process is triggered by a tachometer input. Averaging based on the speed rather than constant time, removes the contribution of asynchronous vibration sources from a time or linear spectral average. Consequently, the contribution of synchronous rotating components is isolated and displayed.

A Synchronous Averaging application is included with all standard Data Physics SignalCalc Dynamic Signal Analyzers.
