Abstract :
To minimize the absolute (or relative) error of signal reproduction the "uniform analog" of the truncate Fourier discrete spectrum is proposed. To put it more exactly, the spectrum with the coefficients of the uniform (minimax, Chebyshev) approximation needs to be used instead of the Fourier coefficients. The algorithm and application examples are described. A decrease in the signal reproduction error of 2 - 20 times is obtained
