Abstract
The direct solution of the problem of multifrequency process analysis meets enormous difficulties. Indeed, the simplest calculation, for example, of a two-frequency process in a dynamic single-frequency parameter system has three frequencies, three amplitudes, and three phases as unknown quantities. Finding a solution in the nine-dimensional space of unknowns concerning a system with many state coordinates is not a simple problem even using modern computer power.
