Moving average

The moving average is the process of assuming the average value of past n times of measured values
which includes the measured value of that time to be a current measured value each time the sampling
of the measured value is performed. The moving average makes it possible to suppress the instanta-
neous fluctuation of the measured value and make the tendency of the measured value easier to see.
The image of moving average is shown below.

Note The sampling of the measured value is performed internally even in the case of the unmeasured state
before the trigger start.
