The establishment of EVISA is funded by the EU through
the Fifth Framework Programme (G7RT- CT- 2002- 05112).
Supporters of EVISA includes:
Observation of a periodically-generated signal at a controlled time
after each repetition is initiated. By averaging many repetitions at a
given delay after event initiation, one obtains a more precise
measurement of the behavior of the repetitive event's time course than
could be obtained with a single observation.
