dc.description This paper describes 2 key characteristics of signals ie the IF and the IB, and, their relationship to defining multicomponent signals. (The most recent upgrade of the original software package that calculates 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). en_US
dc.description.abstract The definitions of instantaneous frequency are reviewed in the context of signal theory, communication theory and discrete time implementations. The spread of a signal about its instantaneous frequency, or instantaneous bandwidth, is investigated for several common time-frequency distributions by simulations. The instantaneous frequency of a multicomponent signal is examined. Further investigation of the time-frequency representation of a multicomponent signal leads to an adaptive algorithm which may improve time-frequency resolution of multicomponent signals. en_US
