Smoothing a Signal Curve

The Smoothing feature allows you to smooth out fast fluctuations on curves by applying a moving average filter. This is often useful for smoothing RPM signals or order analysis. Fast fluctuations may result from imperfections during the recording of (RPM) signal or during the (Order) analysis.

To Smooth a Signal Curve:

  1. Open a temporal signal.
  2. Click a temporal signal.
  3. In Edit, choose Smooth.
  4. From the Smoothing box, define a level of smoothing..
    Note: This parameter controls the length of the window used for the moving average filter:

    - 0% applies no smoothing on the signal curve.

    - 100% applies a smoothing using a moving average filter using a 1-second length window

The signal curve is smoothed.
