Input Signal Averaging

Windowed averaging for stable signal display with fast response

Technical Documentation › Input Signal Averaging

Windowed averaging enables you to average a selected number of input signal samples within a selectable averaging window. This approach provides the benefit of a stable signal while maintaining fast response to changes when needed.

How It Works

The number of input signal samples to average is selected in the [AV_S] menu. The size of the averaging window in input signal display counts is selected in the [AV_W] menu.

As the controller monitors the signal, the averaging window tracks the input and locates a group of samples within the window size. When a new sample enters the controller, the oldest sample in the group is removed. As long as the sample group stays within the averaging window, the controller continuously averages the values.

Response to Signal Changes

If a sample moves outside the averaging window, the controller quickly responds by displaying the non-averaged signal value. Once the signal stabilizes, a new averaging window forms around the sample group and averaging resumes.
