Frolov S.S., Shevelenko V.D., Gusarov A.A. APPROXIMATION METHOD OF SINUSOIDAL EQUAL-AMPLITUDE POLYNOMIALOne of approximation methods of equal-amplitude trigonometrical polynomials having equal permanent discrete spectrum, - approximation method of sinusoidal polynomial is suggested in this article. Analytical expressions for discrete harmonic spectrum of approximate function are given and its determinant characteristics – coefficient of parasite spectrum harmonics and unevenness of harmonics amplitudes at working sphere of spectrum are calculated in this work.
