Resumen
The conventional DFT-oriented nonparametric
interpolation methods, based on time windowing and the
DTFT envelope curve resampling (zero padding, Chirp-z
[1], frequency scale distortion [2], etc.), can improve the
spectrum computational resolution. Two methods
proposed herein involve some modification of the
frequency domain representation and apparently improve
