Abstract: A sample of values of plasma density in a thermonuclear facility is studied. A methodology for processing experimental data that makes it possible to establish correspondence between this sample and a model of nonstationary noise is proposed. This model is formed as convolution of a stationary sequence and a memory function, and it makes it possible to simulate the competition between space and time nonlocalities. A physical interpretation of the nonlocality parameters is described.

Key words: time and space nonlocality, spectral analysis, time series of physical quantities, plasma density.
