Disadvantage: The waveforms
(templates) have to be stored
internally prior to this selection.
Creates the upper and lower
boundary (template) from the
source signal, not from an
internally stored waveform.
Advantage: No need to store the
waveforms prior to this selection.
Disadvantage: The template shape
is proportional to the source
signal. The distance (allowance)
between the source signal and the
upper and lower template is the
same.
