Noise Filtering

To get rid of signal disturbances, the dataset can be modified by a moving average filter (Data > Noise Filtering), 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.

A measurement noise can be identified, for instance, with the amplitude spectrum of the signal (see Amplitude Spectra).

Note
For the diesel engine example, noise filtering is not necessary.
