Abstract

We present the results from high-speed photometry observations of the symbiotic systems R Aqr amd CH Cyg, and symbiotic-like systems Mira AB and MWC560 (V694 Mon). The periodogram analyses show multiple periods (or quasi-periods) in MWC560 and CH Cyg ranging from several minutes to hours.
