Noise Filtering

To get rid of signal disturbances, the dataset can be modified by a moving average filter, where the new signal is generated as follows:

n = filter window size

The window size n is given in time steps, so it depends on the current sample time.

If the sample time is 0.1s and the window size is 10, the moving average window has a width of 1s.

Signal disturbances can be e.g. measurement noise, which can be identified with the amplitude spectrum of the signal.

Set up noise filtering

1. In the main window, select Data > Noise Filtering.

   The Noise Filtering window opens.

   

2. In the Noise Filtering window, enter a value for the window size.

3. Click OK.

4. All datasets are filtered.
