A peak is a measurement point whose value is greater or smaller than the
adjoining measurement points on its right and left sides. Peaks are
classified into the following two types depending on the difference in
magnitude from the measurement points on either side of it.
Positive
peak
(Positive)
A peak whose measured value is greater than those of
the measurement points on either side of it (peak
polarity: positive)
Negative
peak
(Negative)
A peak whose measured value is smaller than those of
the measuring points on either side of it (peak polarity:
negative)
About Peak Excursion Value
The peak excursion value is the smaller of the differences in measured
values from the adjoining peaks of the opposite polarity.
