SHORT-TIME HARTLEY TRANSFORM

The standard Hartley transform is not directly applicable to the repre sentation of signals whose properties change markedly as a function of time. The short-time Hartley transform (STHT), a time-varying Hartley representation of a signal, is therefore introduced. The analysis and synthesis procedures of the STHT system are described in detail. The bulk of the computation in both analysis and synthesis procedures is p erformed by the FHT (fast Hartley transform), thereby making the syste m attractive for implementation, especially if a high-speed FHT proces sor is available.
