  We present a concise report on the '2DHybrid' method, an innovative extension
of two-dimensional correlation spectroscopy (2D COS), tailored for quasar light
curve analysis. Addressing the challenge of discerning periodic variations
against the background of intrinsic "red" noise fluctuations, this method
employs cross-correlation of wavelet transform matrices to reveal distinct
correlation patterns between underlaying oscillations, offering new insights
into quasar dynamics.
