setting is different from when there is no mean processing, as shown in the
following diagram.
2. Specify “no mean value processing” to follow conversion of a rapid change
in input signals.
3. If the averaging function is used, the delay in the conversion data in com-
parison to changes in the input signals will be as shown below.

Using One Word
t = n + (2 to 3)
Using m Words (1
≤ m ≤ 8)
No averaging (n = 1) or two averaging buffers (n = 2):
t = n x (m + 2)
n averaging buffers (4
≤ n ≤ 64):
t = (n

Using One Word
t = n + (2 to 3) x 1/4
Using m Words (1
≤ m ≤ 8)
No averaging (n = 1) or two averaging buffers (n = 2):
t = n x (m + 2) x 1/4
n averaging buffers (4
≤ n ≤ 64):
t = {(n
