Abstract

The comparison of conditional averaging using so-called threshold and template methods is made in their application on quasi-periodic burst of I-mode in ASDEX Upgrade (AUG) I-mode plasma. For obtaining conditionally averaged waveforms, three different manners to determine the 'clocks', using raw signal, envelope of the signal and numerical filtering, are applied to each method. The comparison demonstrates the excellency of the template method to extract typical characteristics of target phenomena in its uniqueness to select the ensemble waveforms and its good convergence property.
