Changes in mean arterial pressure and suprarenal blood flow, manifested under basal conditions or elicited by stimuli applied upon afferent and efferent nerves in the form of a binar noise, have been studied on anaesthetised dogs. Based upon analysis of the auto- and cross-correlograms of the signals, the approximated transfer functions of a section under test of the circulatory system have been determined on an analogue model. Properties of 'useful" and 'noise' components of the signals have been estimated. Stochastic methods were found to be very efficient also in studies concerned with investigation of signals and dynamic properties of the circulatory system.
