    The paper deals with an experimental research of an active boundary layer control achieved by using periodic excitation of a synthetic jet. The main emphasis of the paper is placed on an influence of amplitude modulation of the synthetic jet flow control. It summarizes the influence of the basic factors that affect the design of the synthetic jet actuator, particularly Strouhal number – nondimensional frequency (F+), Stokes number of output orifice (Sto), Reynolds number (Re), momentum coefficient (c). The principle of a flow control with and without amplitude modulation was used in order to generate a lower actuating frequency. An amount of input energy of the actuators that influences the flow filed was measured.
