On the Highest Accuracy of Spectral Estimation of Harmonic Signals by the Discrete Fourier Transform

Yu. E. Ivanov
National Technical University of Ukraine "Kiev Polytechnical Institute", Kiev

RÉSUMÉ

Calculation is carried out of estimation errors using discrete Fourier transform of the amplitude and frequency of a monoharmonic signal. Analytic expressions are presented of upper estimates of the maximum errors which depend on the observation interval and signal sampling frequency. The effect of signal smoothing by the Kaiser window on the errors is studied.
