dc.description This paper defines a methodology for time-frequency filter design with relationship to instantaneous frequency estimation. A software package that calculates IF estimates and TFDs can be downloaded from the web site: en_US
dc.description.abstract An automatic time-varying filter design technique is presented, based on windowing in the time-frequency plane about the IF of the signal under analysis, followed by signal synthesis using the Wigner-Ville distribution. The choice of the IF estimation algorithm determines the performance of the method. Algorithms for IF estimation are presented, and their performance in additive noise is discussed. The method is applicable to automatic filtering of FM signals. A review is presented of the various approaches followed by the authors and others. en_US
