Formation of diadynamic currents with a universal low-frequency signal generator for electrotherapy

In this work, the problem of the formation of diadynamic currents for the electrotherapy was solved with the universal low-frequency generator. The theoretical justification of this generator was made in the previous works. Diadynamic currents are sequences of impulses with a sinusoidal front and an exponential fall. The formation of such currents is made in the universal generator with a three-stage modulation of a quasi-harmonic signal. Each stage has special transformation function. An analysis of the forms of the carrier and modulating signals of the diadynamic currents and their mathematical models made it possible to determine the parameters of the control signals for the modulators and the expressions for the transformation functions on the transition sections. An assumption is made about the biomedical equivalence of diadynamic currents with similar spectra. It has been suggested that it is possible to increase the required therapeutic effect from the influence of a given diadynamic current. It is possible due to the redistribution of energy between sub-ranges of harmonic oscillations. This redistribution is provided by changing the parameters of the control signals in the universal digital generator.
