cross correlation function (CCF)

A cross correlation (CCF) is the mathematically derived correlation between two variables, functions, or signals. This correlation can be done by multiplying the two signals and then integrating the result. If the result, expressed in the correlation coefficient, is zero, the two signals have no relationship; they are uncorrelated or orthogonal.
