Abstract. The structure of the spectrum of the electromyographic signal is the sum of shifted relative to each other on stage from time to time following the pulse. The connection between the statistical properties of the random phase difference and a view of the power spectrum of the signal is found analytically. Results of numerical experiment are given.
Key words: spectral analysis of random signals, mathematical modeling.
