Abstract : We performed the spetro-temporal analysis of the AstroSat archival data of four atoll sources 4U 1728-34, 4U 1820-30, 4U 1735-44 and 4U 1705-440 observed with Soft X-ray telescope (SXT) and Large Area X-ray Proportional Counter (LAXPC) of AstroSat. With the aim of studying the quasi-periodic variability as a function of accretion regime, we also carried out the systematic search of the quasi periodic oscillations (QPOs) in the X-ray time series of theses systems. The result obtained from the analysis will be presented.
