dc.description The B-distribution is objectively evaluated in terms of its ability to represent multicomponent signals with a high resolution, and shown to outperform most other quadratic TFDs. (The most recent upgrade of the original software package that calculates The B-distribution, other Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia., and then continuously updated). A companion is the comprehensive book on Time-Frequency Signal Analysis and Processing available at: http://www.elsevier.com/locate/isbn/0080443354 en_US
dc.description.abstract The properties of the previously proposed B-distribution are investigated. We show that this distribution satisfies most of the desirable properties sought for a time-frequency distribution. That is, we show that the B-distribution is real, time and frequency shift invariant and its first moment with respect to frequency yields the instantaneous frequency of the signal. We also show, using real and synthetic data, that the B-distribution outperforms other quadratic time-frequency distributions in resolving signals' components in the time-frequency domain. It achieves a better time-frequency resolution and a better energy concentration around the instantaneous frequency of the signal, and still significantly suppresses the cross-terms. en_US
