Abstract

In this paper, a number of nonparametric methods that allow a modification in the computational resolution of the discrete spectrum are reviewed and compared according to different criteria. In this way, the most adequate method can be selected for a given application, according to the guidelines given in the paper. Some novel results are given in the analysis of the compared methods, in particular, an approximate method for the calculation of the signal-to-noise ratio using the frequency warping technique
