An accurate and extensive analysis of the present possibility of obtaining definite, unambiguous frequency-spectra solutions for multiperiodic Delta-Scuti stars is performed using artificial data. Some convenient photometric data-sampling techniques are adopted to produce realistic light curves, with gaps and noise and subsequently critically analyzed. Useful suggestions about those to adopt in order to detect very low-amplitude components of the signal have been inferred. The results obtained point out the need for an extensive devoted series of measurements, spread over a very long time span and over a wide baseline of observers.
