Abstract: Systematic survey for multiperiodicity in the LMC Cepheids (Moskalik et al. 2004, IAU Coll. 193, ASP Conf. Ser., 310, 498 and Mem. Soc. Astron. Ital., 77, 563) has led to discovery of several new forms of pulsational behaviour. One of them is periodic amplitude and phase modulation observed in many first/second overtone (FO/SO) double mode Cepheids. In the current paper we present detailed discussion of this newly discovered phenomenon, based on a combined OGLE+ MACHO sample of double mode pulsators.
