Description
Frequency filter is not used.
Ignores frequency components larger than the
specified cut-off frequency. (Only gradual changes
are captured.)
Detects frequency components smaller than the
specified cut-off frequency. (Sudden changes are
captured.)
Detects the frequency components between the cut-
off frequency (lower limit) and the cut-off frequency
(upper limit).
Set this item when a low pass filter or a high pass
filter is selected.
Set this item when a band pass filter is selected.
