Example
This persistence plot of
a bandwidth limited,
smooth waveform
illustrates asymmetry.
Notice that the mid-
level of the 3T
waveform is offset from
0 V, and that the mid-
level of the 11T
waveform is
approximately 0 V.
Since the 3T middle
level is offset, the
expected asymmetry
value is negative. This
is the asymmetry
calculated from a
waveform with several
thousand widths. The
values are the
asymmetry, the 3T
middle level, the 11T
middle level, and the
11T average amplitude.
