Abstract:
   uvby-beta photoelectric photometric observations of the three double-mode 
   high-amplitude Beta-Scuti stars AE UMa, RV Ari and BP Peg are presented. 
   Periodogram analyses are performed using the Fourier Transform Method. 
   In all three stars the power spectra are complex, and a large number of 
   frequencies are identified. For each star, all these frequencies are shown 
   to be harmonics or combinations of two main frequencies nu1 and nu2 
   corresponding to the fundamental and first radial pulsation modes, 
   respectively. Intrinsic b - y, m1, and c1 values are derived and the 
   physical parameters of these stars are determined.
