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.
