Sinc Function based Interpolation Method to Accurate Evaluate the Natural Frequencies

Abstract

Due to leakage phenomena the frequencies and amplitude of the vibration signals given by the sinc function are not indicated correctly. There are interpolation methods that solve the problem of frequency evaluation but which sometimes present significant errors. This paper presents how the real value can be found if the amplitudes are known on 3 spectral lines that are in the vicinity of the actual frequency.
