Autocorrelation Function - University of Delaware
www.physics.udel.eduThe autocorrelation function tells us the time interval over which a correlation in the noise exists. If the noise is made entirely of waves, and the waves move through the plasma (or other medium) without decaying as they travel, the autocorrelation will be large for all time. 1 1 1 ( …
