We present a power spectral density analysis of the 1-minute cadence Kepler light-curve data of the cataclysmic variable V1504 Cygni. We identify three distinct periods: orbital period, the superhump period, and the infrahump period. The results are consistent with those predicted by the period excess-deficit relation.
