Abstract: The frequency characteristics of the device for measuring estimates of Lyapunov characteristic function (c.f.) of random processes are investigated. Based on the equations of estimates of c.f., a model was developed for measuring the estimates of the real and imaginary parts of the Lyapunov function. As a result of the study of the model, the amplitude-frequency characteristic of the device was experimentally obtained. The results obtained indicate that the amplitude-frequency characteristic of the device for measuring estimates of the Lyapunov function varies significantly depending on the amplitude of the input signal. Under various conditions, the device can be equivalent to a low-pass filter or a multi-band filter.
