Bulatov V.N., Khudorozhkov O.V., Semeonov A.P. TECHNIQUE OF THE DIGITAL SPECTRAL ANALYSIS OF SIGNAL WITH IRREGULAR SAMPLES ON TIMEIn article the technique of drawing up of a polynomial on samples of values of a signal with non-uniform digitization on a final interval of time is presented. For an approximating polynomial expression of spectral density is resulted and on its basis expression line a spectrum for the registered file loadout a signal with irregular digitization is formed. The made technique allows to make the digital spectral analysis of signals for discrete transformation Fourier with non-uniform sample on time of their values.Key words: a signal, interpolation, spectral transformation.
