FIELD: electric engineering.
SUBSTANCE: method includes multiplying a total of even number of N results of multiplication of previous logged values of signal by appropriate values of total of N/2 late members of row of complex Fourier row by 2/N, while momentary values of said total of Fourier row is reproduced as amplitude modulation of cosine oscillations of bearing frequency, exceeding in (N+2)/4 times the circular frequency of signal with length T, with law of alternation of circling line of amplitude-modulated oscillation, determined by relation of momentary values of sine oscillations of equal amplitudes, frequency of dividable sine oscillation in N/4 times greater than circular frequency of length signal T, and frequency of sine oscillation of divisor twice less than circular frequency of signal.
EFFECT: broader functional capabilities.
