5.10 Averaging Inputs
Averaging is a function that makes display and output smooth for input values with dramatic fluctuations,
such as spike noise.
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 average is used when the display refresh period is to be lengthened.
Moving average is used to remove periodic noise superimposed on input signals.
The relationship between the data refresh periods for both simple and moving averages when the
averaging times is set to 4 is shown below.
