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.
