Spectral warping is a time domain to time domain transformation on a signal that effectively warps the frequency content of the original signal. Here we present a matrix formulati...

Harmonic distortion may be characterised by the proportion of energy of a sinusoidal signal transferred to the harmonics. Differential time scaling resulting from the spectral war...

A DSP technique that transforms a digital signal by warping the frequency axis is discussed. The technique corresponds to a mapping of the samples in the z-domain such that they a...

This paper aims to introduce the robustness against noise into the spectral clustering algorithm. First, we propose a warping model to map the data into a new space on the basis o...

We revisit the topics of near-field adaptive beamforming and source localization following an alternative approach based on a spatiotemporal spectral representation of the acoust...
