RollingAverage samples the value on property input when triggered by the placement of any value on property triggerSample. It keeps track of the number of samples specified in property sampleCount, and places the mean of its stored samples onto property output.
This means that RollingAverage is useful for "smoothing out" continously-changing values produced by other components.
Components Timer or CounterTimer can be used to generate a periodic sampling trigger for RollingAverage.
