5.9 Averaging Input

Average processing of input values smooths the displays and outputs for inputs with extreme fluctuations,
such as spike noise.
Explanation of Functions
There are two types of averaging: "simple" and "moving." Select one type. The number of samples
("averaging times") can also be specified for the input values to be averaged.
Simple averaging is used when the display refresh period is to be lengthened. Moving averaging is used to
remove periodic noise superimposed on input signals.
The following graphs show the relationship between the data refresh periods for both simple and moving
averaging processes when the averaging times is set to 4.
