Abstract

The eclipsing variable PP Lacertae has been examined on the basis of two light curves (V andB) analysed by means of the Fourier analysis of the light changes in the frequency domain, taking into account the perturbation and distortion effects of both components.

A set of geometrical and physical elements for the system is obtained from both minima, through their magnitude variation during the observation time. The system has been discussed according to the behaviour of the light curves.
