Light curves and power spectra of a given Delta Scuti model were synthetically constructed in order to investigate the effects of different techniques of photometric data sampling on the final structure of the periodograms. The main purpose of this analysis is to provide suggestions for the interpretation of periodograms obtained from real light curves of multiperiodic variables. Results point out that an unambiguous detection of the pulsation modes from the periodograms is difficult also in the case of very long runs of observation and that maybe only international observing campaigns could provide the most useful photometric data sampling technique.
