Abstract

Instantaneous frequency can be defined, following Taner, Koebler and Sheriff (1979), as the differente in phase between two adjacent samples in a complex time series; the two parts of the time series are related by the Hilbert transform and they define a functian whose spectrum is zero for negative frequencies. The frequency attribute is often noisy and its ability to present useful information will depend on a well designed colour display. This is of minor importance for some applications but there are potential uses whose development requires an improvement in quality.
