Approximation of Function with Breaks. Method of Demodulation of a Complex Signal |
D.B. ROZHDESTVENSKY
The problem of approximation of function with ruptures is solved. The decision is based on representation of final sample of equidistant readout, as result of modulation of a complex signal. Using methods of formation of the signal limited on a spectrum, initial sample of a discrete signal is transformed to the peak-modulated signal. Peak demodulation has allowed to receive a signal which is approximation of an initial signal, free from distortions because of Gibbs-phenomenon.
Keywords: approximation, modulation, a spectrum
