Excluding Samples from the Ensemble
Excluding a decay will exclude all
frequencies for the selected decay.
When the display is showing data for an individual decay,
the operator has the option of excluding the current decay
from the ensemble average. Excluding decays from the
ensemble is useful when one or more are corrupt, as is
evident in FIGURE 15-21. In this case, the operator coughed
during a measurement.
Once the data has been stored, it
cannot be edited in the Model 831;
therefore individual decays cannot
be included or excluded from the
ensemble.
