Abstract:
In this paper a three-point interpolated
discrete Fourier transform (IpDFT) method for
estimating with high accuracy the frequency of a
multifrequency signal component is presented. The
performance of the proposed method has been analyzed
by means of computer simulations for a multifrequency
signal without noise and with quantization noise as well.
