| Abstract: | Based on the sampling theorem that the spectral envelope of signal can be reconstructed from its data samples, a simple and practical interpolation is proposed in this paper, and the effectiveness of it along with the superiority of FFT is suitable for the zoom of frequency resolution, specially for the cases that acquisition of more spectral information of signal from data samples is needed. |
