Part I of this paper introduced the hyperbolic class (HC) of quadratic/bilinear time-frequency representations (QTFR’s) as a new framework for constant-Q time-frequency analysis. The present Part II defines and studies the following four subclasses of the HC: • The localized-kernel subclass of the HC is related to a timefrequency concentration property of QTFR’s. It is analogous to the localize...

A methodology that combines information from several nonstationary biological signals is presented. This methodology is based on time-frequency coherence, that quantifies the similarity of two signals in the time-frequency domain. A cross time-frequency analysis method, based on quadratic time-frequency distribution, has been used for combining information of several nonstationary biomedical si...

This research note proposes a new view of audio time-frequency analysis as a probilistic inference problem. That is, given an incoming signal, the goal is to infer the underlying the time-frequency coefficients using Bayes’ rule. The note begins by building a bridge between this inferential view of audio time-frequency analysis and traditional approaches, providing examples of inference problem...

A procedure for logo watermarking of speech signals is proposed. In order to take full advantage of both time and frequency domain, we have used joint time-frequency representation of speech signal, which provides a more comprehensive information compared to each domain individually. Time-frequency based selection of the Discrete Fourier Transform (DFT) coefficients is used for logo embedding. ...

Although a beating tone and the two pure tones which give rise to it are linearly dependent, the ear considers them to be independent as tone sensations. A linear time-frequency representation of acoustic data is unable to model these phenomena. A time-tone sensation approach is proposed for inclusion within audio analysis systems. The proposed approach extends linear time-frequency analysis of...
