Scientific paper

We have investigated the usefulness of wavelet analysis for studying the changing period and amplitude of small-amplitude pulsating red giants. Specifically, we have applied it to EU Del, W Boo, and SX UMi. With care, this method can provide useful information about variables with amplitudes between 0.2 and one magnitude, especially if used in conjunction with light curves, Fourier analysis, and autocorrelation analysis.
