Frolov S.S., Shevelenko V.D., Burkova E.V. METHOD OF APPROXIMATION OF EQUAL AMPLITUDE POLYNOMIALLow effectiveness of modern measuring signals using for measuring of frequency characteristics in the sphere of infralow frequency is shown in this article. New signal – trigonometrical polynomial with equal discontinuous spectrum and method of its approximation are suggested here. Analytical expressions of discontinuous harmonic spectrum of approximation function are got. Methodic of approximation errors appraisal in the form of stray spectrum harmonics coefficient and unevenness of amplitude spectrum at working time is offered in this work.
