What is Time Frequency Analysis?
Time frequency analysis provides a joint time-frequency representation of a signal. Using newly developed methods, one can often separate the components of a signal in ways that are difficult or impossible using time-series or spectral analysis. RID The Reduced Interference Distribution or RID results when certain design principles are followed. A large variety of different designs can be achieved, all with the goal of providing high resolution time-frequency representations. All of these representations exhibit many desirable properties such as correct time and frequency marginals, proper time and frequency support, proper instantaneous frequency and group delay characteristics and, most importantly, considerably reduced interference when compared to the well-known Wigner-Ville distribution.
